This family sounds like it might be a match, as I believe both the names Michael and Jeremiah may be in Catherine's family.We've been told by sources in Ireland that her father's name was Jeremiah Lane but I also have a baptismal record from Donoughmore (7/18/1816) that indicates a Catherine Lane was born there to John Lane and his wife whose maiden name was Keliher.Of course it is always possible that was a different Catherine Lane, but we know "ours" was born about 1816 to 1817 so it is an awfully close match.There was also a baptismal record for Mary Lane, dau of John born in 1815.
Catherine Lane married Daniel Mahony in 1836 and their first child, Daniel was baptised 1/15/1837 in Donoughmore.They had 7 other children in Ireland.Daniel came to the U.S. in about 1851 and Catherine followed with three children (Daniel, Catherine and Jeremiah) in 1853, landing in New Orleans.Most likely the other children had died during the interim, though it is always possible a very young one might have stayed behind with family or friends.
Tragically, Catherine then died on August 16, 1853 and is buried in St. Patrick's cemetery in New Orleans.Her tombstone mentions that she was "a native of Donoughmore, Co. Cork" and that she was 36 years old.Buried with her is Elizabeth Falvey, who died the next year (Sept, 1854) and was 50 years old.We don't know for sure if the Falvey connection was on the Lane side or the Mahony side (or perhaps both, judging from some of the birth and marriage records in Donoughmore).
Daniel Mahony subsequently remarried to another Catherine and they had two (and possibly three) children.Daniel the son (b. 1837) eventually moved to Dubuque County, Iowa and settled in Vernon Township.When he first arrived there (about 1856) he lived with a Lenihan (or Linehan) family who were supposedly cousins of some sort.Again, we don't know if the connection was on the Mahony side or the Lane side.Catherine, the daughter married Patrick Burns and lived the rest of her life in New Orleans.Jeremiah moved around quite a bit but eventually settled near Manchester, Iowa (his biography appeared in the county history and confirms the tombstone and other information).
Well, that is a quick synopsis of what we know about Catherine Lane Mahony.I wish we had more on her in Ireland.I need to check my records again and then will post the two Lane marriages I have from Donoughmore (one in 1800 and the other about 1812 or 1814 as I recall).Do you know the dates for Michael and Jeremiah Lane in your husband's family?
