George John Hack

Born in 1887 and died in 1935.

born 2 Oct 1887 died 20 Dec 1935

George John Hack was born on 2 October 1887, according to a Veterans Administration index entry that the old family tree cites.1 On 19 October 1911, at Wadena, in central Minnesota, he married Blanche Estelle Isherwood, who was eighteen.2 They had a son, Vincent Hack, who in 1969 was living at San Antonio, Texas, when his stepfather, Robert Lucius Hegnauer, died in California.3

The marriage ended, by divorce or by George's death, before November 1930, when Blanche married Robert Lucius Hegnauer in North Dakota (see her profile). The same Veterans Administration index gives George's residence as Farmington, Minnesota, and his death on 20 December 1935.1

Research notes

  • Sources: The Minnesota marriage index (MOMS; the bride's line read 27 Sep 2026) and his stepson Vincent's mention in Robert L. Hegnauer's obituary (page read). His birth, residence and death come from the U.S. Veterans Administration master index as the old family tree cites it; that entry has not been read.2, 3, 1
  • Military service: A VA master index entry (1917–1940) implies that he served in the armed forces, most likely in the First World War; his WWI draft registration (1917–1918, Minnesota) and any service record should be looked for.1
  • End of the marriage: If he died in 1935, the marriage must have ended earlier by divorce, since Blanche remarried in 1930. A Minnesota divorce record (1920s) is the next search.1
  • Leads: the VA index entry itself (FamilySearch ark 1:2:QT96-NKFY); the 1920 census of Minnesota (George, Blanche and Vincent Hack); a Minnesota death record (Dec 1935) and burial (perhaps a veterans' headstone application).
  • This profile is part of the Hegnauer one-name study, as the first husband of Blanche Estelle Isherwood, the second wife of Robert Lucius Hegnauer.
