Dorothea - We may have communicated in the past but I am not sure - I had a PC problem and lost all of my emails.
My grandfather was Andrew Brennan, b1812, son of Andrew Brennan whose wife was Cathy Maher. My grandfather's sibs were: John b1798; Ellen b1811 and Philip b1813. All were born in County Tipperary. John and Andrew immigrated to PA in the mid 1800s. John's wife was Johannah Fogerty and Andrew's (first) wife was Mary Treacy/Tracy. Andrew remarried Catherine Lynch in PA after Mary died. I am a descendant of Andrew and Catherine.I have extensive info on Andrew and John and their descendants but lack details on their parents. Looking forward to hearing from you.
