Hi, Greg. I just don't know if this is the right John Cromer as I am trying to "connect the dots" so to speak. My gr-great grandmother, Mary A.Cromer married Jacob Clayton Blackstone in Richland Co.OH, abt 1834. She was born abt. 1816, and had a sister Margaret, b. ca 1814, living with her in the 1880 OH census. Do you know if John had sisters Mary and Margaret? I'm not sure if Margaret ever married. Since I cannot find who was Mary Cromer's father, I am trying to trace on her siblings. Since John's daughter, Amanda, married Allen Blacksten(Blackstone)and Allen was the son of Jacob and Mary Cromer Blackstone, which seems to have been a cousin marrying a cousin, that may lead me to the right Cromer family. What can you tell me about John's siblings? Do you have any info on Allen Blacksten and Amanda Cromer? Any help appreciated. Thanks.
