Beth is in an assisted living arrangement in New Orleans. She will celebrate her 90th birthday soon with a trip to Europe on a cruise which will pass near Colmar and Wintzenheim in the Alsace region where Emile Bloch, Ted's great-grandfather was born in 1824. Ted asked if I could help him use JewishGen to find more of the Bloch family there.
I found was the town page for Wintzenheim/Winzenheim, which is close to Colmar.
There are links on that page to other resources; JewishGen French SIG and JewishGen Ger SIG which may be helpful. (Nearby is the town of Turkheim, where Sally Steinhardt's husband David Turkheimer's family is from.)
While looking at FamilySearch I found a Louisiana Naturalization record for Emile Bloch which Ted may not have seen.
Hannah Banks is another researcher on Ancestry who has a record for Emile Bloch, but she does not show any ancestors. She does show his brother Leon Bloch and a link to his grave. Ted already his a photo of his gravestone.
