My great-great grandparents were Arthur (d. 1916 in france) and Celina Delbeck Balon from Besançon, France. Celina came to the US in 1916 with daughters Berthe and Gabrielle. Some time after 1924 Celina moved to Baltimore with her daughter Berthe and son-in-law Michael Pillires.
I cannot find these people on the 1930 census and the only proof I have that they were in Baltimore are Michael's WWII registration from 1942 and Michael's and Berthe's Death Index. I have nothing on Celina.
