David Tobin (c. 1918–1967)

Paternal grandfather of Brendan Tobin; father of Thomas Tobin (b. 1953); husband of Margaret Ziebold. Family-provided details are approximate (b. ~1918 NY, d. ~1967 NY).

CONFIDENCE: UNVERIFIED. Source-confirmation passes — including a deep search with WIDENED year ranges (birth 1914–1922, death 1963–1971) — found no matching record. 'David Tobin' is a very common name and 1960s New York deaths are poorly indexed online; the New York David Tobins located (e.g., b.1930 Bronx d.2007 FDNY; b.1962 d.2016 Rochester; b.1920 d.2011 Hewlett; d.2003 Buffalo) do not fit b.~1918 / d.~1967. No Find A Grave memorial or SSDI entry matched.

Best next steps: order the NYC death certificate via direct-descendant access (NYC Vital Records / Municipal Archives); locate the Tobin–Ziebold marriage record; and check the free 1950 US Census for the household.
