We are researching Greer ancestors from Corlust, Armagh and believe that the William Greer who married Elizabeth Dermitt (Dermott) is the son or Moses Greer and his wife Isabella (Bell). If he is, he would have been their fourth son. Wm and Elizabeth had three children prior to 1866 (including a son, Richard) when they left for Wabasha, MN. We are trying to confirm that William's parents were the same Moses Greer, a Corlust Farmer at the time of Wm's second marriage in 1860, and Bell. On a trip last year to PRONI, we found the records of the births of their first three sons, John (1825), Alexander (1827), and Samuel (1828). Any help that would confirm William as their third son, born in 1830, would be greatly appreciated!
