Meryl Streep is one of the most recognized actresses in the world. But the family that raised her has largely stayed out of the spotlight — and that starts with her father, Harry William Streep Jr.
Most people have never heard his name. He wasn’t a celebrity, a public figure, or someone who sought attention. Yet he shows up regularly in genealogical research, ancestry profiles, and biographical notes about his famous daughter. This article looks at who he was, what we know about his life, and why his name still generates interest today.
Who Was Harry William Streep Jr.?
Harry William Streep Jr. was the father of actress Mary Louise “Meryl” Streep. That is the detail most people are looking for when they search his name, and it checks out across multiple sources.
By profession, he was a pharmaceutical executive. That’s the occupational label that appears in biographical notes about Meryl. No specific employer name or job title is documented in reliable public sources — he simply wasn’t the kind of person who left a detailed professional footprint in the public record.
His wife was Mary Wolf Wilkinson, described in genealogical records as a commercial artist and art editor. Together, they built a middle-class professional household in New Jersey and later Connecticut — pharmaceuticals on one side, commercial art on the other.
Beyond his relationship to Meryl and his occupation, Harry Streep Jr. lived as a private individual. Most of what we know about him comes from brief contextual mentions in profiles of his daughter, not from standalone coverage of his own life.
Birth, Death, and the Record Discrepancies Worth Knowing
The confirmed facts about Harry Streep Jr.’s life dates are straightforward, though the details shift slightly depending on the source.
His birth is listed as October 3, 1909 or 1910, in Newark or Essex County, New Jersey. Find A Grave and FamilySearch both record 1909, while Geni and Familypedia list 1910. His death date is consistent across sources: July 22, 2003, in Stamford, Fairfield County, Connecticut.
There’s also a name variation worth noting. Some records list him as Harry William Streep Jr., while others — including Find A Grave and FamilySearch — record him as Harry Wilbur Streep Jr. The Geni profile uses William; FamilySearch uses Wilbur.
These kinds of small differences are common in genealogical records. A birth year off by one, a middle name recorded differently — these often come down to transcription differences between original documents and later database entries. It doesn’t mean the records are pointing to different people. It just means that no single source should be treated as the final word without corroboration.
Think of it like comparing an old family Bible entry with an official birth certificate. Both can be genuine, and both can disagree by a year. Genealogists note the discrepancy rather than picking one version and ignoring the other.
His Children — Meryl Streep and Her Brothers
Harry Streep Jr. and Mary Wolf Wilkinson had three children. Meryl Streep was the eldest, born June 22, 1949, in Summit, New Jersey. She was followed by two younger sons: Dana David Streep and Harry William Streep III.
All three children appear across genealogical records and biographical summaries of Meryl’s background. The family is consistently described as a professional, middle-class household — one shaped by a father working in pharmaceuticals and a mother working in commercial art.
Meryl has occasionally spoken about her parents in interviews over the years, usually in warm but general terms. The details available in public records don’t go much further than that. What we can say with confidence is that Harry Streep Jr. was a present and working father whose career provided stability during Meryl’s upbringing in New Jersey.
The Streep Family’s German and Swiss Roots
One of the most frequently referenced aspects of Harry Streep Jr.’s background is his European ancestry. His paternal line traces back to Germany and Switzerland — a detail that often surfaces in heritage profiles of Meryl Streep.
On the German side, one documented line leads to Loffenau, Germany. A second great-grandfather named Gottfried Streeb emigrated from Loffenau to the United States. Notably, an ancestor in Loffenau also served as mayor of the town — a detail that adds a small but interesting historical layer to the family story.
Over time, the family surname shifted from Streeb to Streep. This kind of change was common among immigrant families. Names were sometimes anglicized by choice, and sometimes simply recorded differently by clerks who wrote what they heard. Either way, the transition from Streeb to Streep is well documented in the family’s genealogical records.
A separate branch of Harry Streep Jr.’s paternal family came from Giswil, Switzerland. So his roots represent a blend of two neighboring Central European countries, both with strong emigration patterns to the northeastern United States during the 19th and early 20th centuries.
This ancestry is worth understanding in context. When Meryl Streep’s German or European heritage is mentioned in profiles or interviews, it traces directly through her father’s line — through Harry Streep Jr. and the generations before him.
Mary Wolf Wilkinson: The Other Side of the Family
Harry Streep Jr.’s wife, Mary Wolf Wilkinson, brought a different set of roots to the family. Her ancestry is described as English, German, and Irish. Some of her ancestors lived in Pennsylvania and Rhode Island and were descended from 17th-century English immigrants.
Mary Wilkinson passed away in 2001, two years before Harry Streep Jr. She is identified in genealogical records as a commercial artist and art editor — a creative professional background that complements the more corporate world her husband inhabited.
Together, the Streep and Wilkinson lines represent a fairly typical American story: European roots, immigrant ancestors, and a family that eventually settled in the mid-Atlantic states and built a professional life there.
Why His Name Comes Up in Genealogical Research
Most people who search for Harry William Streep Jr. aren’t starting with him. They’re starting with Meryl Streep and working backward.
Genealogy platforms like Geneanet, Geni, Find A Grave, and FamilySearch have made it easy to explore celebrity family trees. Someone might be tracing their own ancestry, find a connection to Loffenau, Germany, and then notice that Meryl Streep’s paternal line also runs through that town. That’s the moment Harry Streep Jr.’s name appears — as a link in the chain between a famous actress and her European ancestors.
Sites like Famouskin specifically build tools around this kind of curiosity. They map out family groups, including Harry Streep Jr. as Meryl’s father, and allow users to explore potential distant connections. For people interested in genealogy, that’s genuinely useful information.

A Private Man Behind a Famous Name
Harry William Streep Jr. died on July 22, 2003, in Stamford, Connecticut. He lived into his early 90s, by most accounts, outliving his wife by about two years.
He left behind no major public record of interviews, memoirs, or personal statements. What he did leave behind is a documented family line — a pharmaceutical career, a household that raised one of the most celebrated actresses of the modern era, and roots that stretch back across the Atlantic to small towns in Germany and Switzerland.
That’s not a small thing. It’s just a quiet one. And in the world of celebrity genealogy, quiet lives often turn out to matter quite a bit once someone starts asking questions.
Harry Streep Jr. is a good example of how many celebrity parents remain essentially private citizens throughout their lives. The biographical detail available on him is mostly occupational and genealogical — not anecdotal or personal. And that’s worth respecting as much as it’s worth noting.
