I am trying to track down a Patrick Donlon family. Migrated to US before 1847. Had a daughter born in Steuben County 1847 , another 1849 and a son 1852. The family does not show up in the 1850 , 1855, 1860 census for Steuben County but is there in 1865. Patrick had a brother John who was in Steuben County and it is possible that Patrick's wife Catherine went there to be with John's wife when Catherine was going to give birth. . Patrick as a family does not show up in PA , NJ , Conn or Mass census for 1850 or 1860 and does not appear per Census of 1850 and 1860 to be in NY. Could it be he was working on the Canal which was being rebuilt at the time? . What New York Counties would this have been? The NY census for 1855 must be check for each county. Any suggestions....
