Hello. I am hoping someone can help.My great grandfather is James Meenan. He later married Annie Dugan. He was a glassblower.My problem is there are two JAMES Meenans, within a year of one another--in the 1860 census from PGH. ONe lives with mother, Catherine (45); the other lives with six siblings, parents are John (innkeeper) and Sarah.Is anyone studying this line??Thanks for any info you have!!!
