This is a Message Board Post that is gatewayed to this mailing list. Surnames: Costelo, Costello Classification: Query Message Board URL: http://boards.ancestry.com/mbexec/msg/an/Qk.2ADI/2045.1.1 Message Board Post: Interesting! I have Thomas J. Costelo b Dec 17, 1846 (1852 Carleton 0ntario Census) married to Elizabeth Nutterville but their daughter is Mary Elizabeth Costello b Nov 22, 1874. Other Costelo/Costello posibilities would be John H. Costelo and Margaret Burnett - their dau Mary b 1850 (1860 Iowa census); there is also Thomas Costelo & Ann Kilroe's daughter Mary b April 2, 1849 Canada. I suppose the key will be in the naming pattern of their children. Could you supply?
