I am hoping someone can assist me on my husband's Fathersancestors.His Father was adopted and has given me the below information.Would be most obliged for any information that I can find on the Angle/Smith Families.

My biological parents names were:

I was born on January 13, 1936.
I was adopted in Logansport, Indiana on the 16th of April in 1937 in Cass County Indiana Case 10977.At that time my adopted mother was
spelling her name Catherine C. Schwartz (per court record) and my name changed at that time to Paul Thomas Schwartz. [Clerk Cass Circuit Court of
