There have been other times in my years of genealogy research when re-visiting the records for a family turn up something new that answers some long standing questions. This happened recently with my Bannon family from County Fermanagh, Ireland and New Haven, Connecticut.
The Bannon family emigrated to New Haven in the mid to late 1850s. They settled in a block of buildings on what was first called “Governeur’s Lane” and later renamed to “Madison Street”. I started calling the area the “Bannon Compound” as there were so many Bannons and relatives living in the houses over the years. My direct ancestor, James Bannon and his wife, Bridget McHugh, lived on Madison Street for the longest amount of time, into the 1880s.

The star marks Madison Street, New Haven, CT in 1868.
In the 1860 census there was a Catherine Bannon living on Madison Street. I originally thought that she was the widow of a Bannon male, although I never found a husband for her. I eventually made the connection that the Joseph Bannon, who was living there and who had immigrated with James and Margaret Bannon earlier, was actually Catherine’s son. At that time I still thought that Catherine was the sister in law of the younger James Bannon. My original report on the family lists her as such. I was aware that Joseph Bannon’s death record only lists his mother as Catherine Bannon, but figured that could just mean that the informant had no idea what his father’s name was.
