I am married to Rosemary Kadan. Her father was J.Earl Kadan, who was born in Baltimore. Earl's siblings were Florence, Oscar Daniel, and Lillian. His father was James Albert Kadan, b. in Bohemia in 1872, d. Baltimore in 1933. James was the son of Frank G.Kadan and Frances Hranicka. They were buried in Baltimore, and I found something indicating that the names on their gravestones are Franzitek and Frantiska. So it is likely that these persons are the ones who witnessed your father's baptism. I have a note that Frank/Franzitek's father's name was Jacob.
PLS ADVISE re how you are related to the Baltimore Kadan family! Thanks!.
P. S. Census records indicate that James Albert was a tailor, as were his brothers Slater Kadan and Emil J.Kadan. Emil married Frances, and their son was Ferdinand Kadan.
