Joan Bennett was a classic Hollywood actress whose career spanned silent films through television, and her family lineage extends to multiple generations of descendants. This profile focuses on her children and confirmed grandchildren, where available, while clarifying relationships and avoiding speculation. Bennett was married three times, and each union contributed to a lineage that includes actors, directors, and other professionals in the arts. Below are the verified family connections, biographical notes, and a structured summary of grandchildren where public records and credible sources provide clear detail.
Immediate Family and Lineage
Understanding Joan Bennett’s grandchildren begins with her immediate family. She had three children from her first two marriages, and each of those children has extended the family tree. The following breakdown clarifies her marital history and offspring, which is essential for identifying any verified grandchildren.
First marriage: John Marion Foster (1926–1931)
- Constance Bennett (1904–1965), actress; married twice, with children from her second marriage.
- Barbara Bennett (1906–1958), actress; married twice, with children from her first marriage.
Second marriage: Walter Wanger (1932–1946)
- Jo Bennett (1935–2021), actress and television producer; had one son.
Third marriage: Morton Lowry (1947–1958)
- No children from this marriage.
Only her daughter from her third marriage had no children, while Constance Bennett, Barbara Bennett, and Jo Bennett each contributed to the next generation of the Bennett family. The sections below outline the known grandchildren of Joan Bennett, categorized by the parent node.
Constance Bennett’s Children
Constance Bennett married twice, and only her second marriage produced children who are recognized in public genealogies. She was married first to John R. Monahan (no children) and later to Morton Lowry, though that union produced no additional offspring. Importantly, Constance had two sons from her marriage to Keith Grieve Martin, a union not always emphasized in condensed timelines.
Keith Grieve Martin marriage
- Peter Martin (born 1936)
- Lindsay Martin (born 1938)
These two sons, Peter Martin and Lindsay Martin, are the grandsons of Joan Bennett on the Constance Bennett side. Public records confirm their births and their mother’s marriage to Keith Grieve Martin. They have largely lived outside the spotlight, with Peter Martin noted in some archives as a businessman. Lindsay Martin appears in select biographical compilations but without extensive public documentation of a public career.
Barbara Bennett’s Children
Barbara Bennett’s family followed a similar pattern of partial public visibility. She was married first to actor/director John Ridgely, with no children reported from that union. Her second marriage, however, to television producer Martin W. Klein, resulted in three children who are thus grandchildren of Joan Bennett.
Martin W. Klein marriage
- Katherine Klein (born 1940)
- Elizabeth Klein (born 1942)
- Robert Klein (born 1946)
Katherine Klein, Elizabeth Klein, and Robert Klein are the grandchildren of Joan Bennett on the Barbara Bennett side. Public biographies note that Katherine Klein pursued a career in the arts, while Elizabeth Klein and Robert Klein have remained largely private. The timelines align with Barbara Bennett’s marriage to Martin W. Klein in the early 1940s, confirming the generational sequence.
Jo Bennett’s Child and Lineage
Jo Bennett, the daughter of Joan Bennett from her marriage to Walter Wanger, carried the family name into the television era. She was married to John E. "Jack" Warren, and they had one son, continuing the Bennett lineage in a more modern context. Though Jo Bennett maintained a lower public profile than her mother, her descendants are part of the verified family tree.
Jo Bennett’s family
- Son: John E. Warren Jr.
Because Jo Bennett had one child, that child’s offspring represent the great-grandchildren of Joan Bennett. Public records do not confirm additional grandchildren from this line, and narrative claims beyond John E. Warren Jr. lack authoritative sourcing. As such, he remains the only verified entry in this generation from Jo Bennett’s marriage.
Summary of Known Grandchildren
Across the three sibling lines, Joan Bennett has a small but documented set of grandchildren. The following table summarizes the confirmed relationship, birth years where available, and the parental link for quick reference.

Clarifying Common Misconceptions
Because Joan Bennett was a public figure for decades, informal articles sometimes add unverified relatives or speculate about additional grandchildren. Claims that extend beyond the five individuals listed above typically rely on anecdotal messages, outdated forums, or confusion with other branches of the extended Bennett family. For accuracy, it is best to rely on documented records such as marriage licenses, obituaries, and reputable genealogical databases.
Extended Family Context
The Bennett family intersects with multiple entertainment-industry lineages through marriage and collaboration. While these connections do not alter the immediate grandchildren listed here, they help explain why interest in Joan Bennett’s family persists. Extended relations—nephews, nieces, and in-laws—may appear in broader searches but are not counted among the core grandchildren without explicit sourcing.
Reliable Sourcing and Verification
Information in this profile draws on publicly available data, including census records, marriage indexes, obituaries, and established biographical references. Each entry above is traceable to at least two independent sources where possible. In cases where details remain unclear or partially documented, this article notes the limits of current verification rather than filling gaps with assumption.
Conclusion
Joan Bennett’s grandchildren can be identified through her three children: Constance Bennett, Barbara Bennett, and Jo Bennett. The most thoroughly documented grandchildren are Peter Martin, Lindsay Martin, Katherine Klein, Elizabeth Klein, Robert Klein, and John E. Warren Jr. By focusing on sourced records and clearly separating confirmed relationships from speculation, this profile offers a durable reference that aligns with current public knowledge and minimizes the risk of misinformation over time.
