My GG grandfather Robert( b. 06/17/1837), born in Tyrone Co. Ireland had a brother William born 09/30/1841. His Parents were Hugh Phair (b. 04/08/1813, Tyrone Co.) and Jane Crawford.Robert's other siblings are Elizabeth (b.08/0/1844), Edward(b.1835), and Anne Jane(b.02/12/1848). I found the repetition of names in your line interesting. BTW Hugh's father was Edward. Edward's father was Samuel. I have more dates, spouses and other children if you think it applies to your family.
