In Columbus, there were several Bresnahan families that I have gathered facts pertaining to their family-
(1)This group I believe could be of my family includes two sisters they married two men of the surname Lyons, that quite possibly could be brothers.
Information is below.
(2)This group includes other Bresnahans located in the Columbus area, but am not sure of the connection.
Bresnahan Group 2
Please understand that time and records do not help to connect all the Bresnahans together. In my opinion they could all be related or just individuals that came to the Columbus about the same time. If anyone has knowledge of these families and would like to contribute please email me.
