'Hans Graff, b. c1672. d. 1746, Earl Township. ... md 1) first wife in about 1698, name unknown. ... Hans's first wife's name is unknown and he had one son by her named Jacob.'
'Hans was said to have been married twice, first was to Ursula Neukomm about 1683, and believed to have had one child through the marriage.'
The note in Find a Grave confuses two different Hans Graff's - one who lived and died in Switzerland (who married Ursula Neukomm, who also died in Switzerland) and one who immigrated to and died in Pennsylvania and whose first wife's name is unknown.
