Thank you so much for that Dathai.
I have to go back to basics on my McGuirk research. I have all certs and connections to 1850 in Blackrock, Co Dublin. then when I found a grave in Deansgrange for my Gt grandfather Richard McGuirk it had an unexpected soldier Peter mcGuirk, buried there 1868 aged 35 years.I have found reference to a Peter McGuirk born Derrylossry, Wicklow about 1833.Also found the same Peter in the 1851 English Census...soldier East india's Company Depor, Warley Barracks. Tara from rootschat found a baptism for Peter 1831 at Glendalough son of Richard and Sarah..correct names so I am taking this as good.
From Deansgrange cemetery info Sarah died in 1870 at 55yrs and Richard died in 1878 at 76 yrs.
I went off on a complete tangent looking at the McGuirks in Tonygarry and Glencree trying to establish a connection and lost sight of the Derrylossry bits.
A Richard born approx 1801 was in Wicklow jail 1846..found this on Mormons site and went to the jail last week to look at the place...fascinating visit...while there a chance conversation with some Wicklow people who were related to a branch of McGuirks rekindled my interest in Raheen.
I have to get back to basics and look for births around Glendalough for Richard and Peter and marriage of Richard and Sarah..remember I saw Parker as a surname for her mentioned in some doc....and see if I can find a connection.Can't believe I spent so much time down the cul de sac !!
