Thanks for your reply Mike. Some of the Birdwood Toomey"s are my ancestors according to my research. I am comfortable with my findings from the present day (me) back to William I mentioned in my original post. From looking at the list of baptisms in this sites Parish Records, there are at least two sets of Toomey parents who could be my William's parents. i.e. Richard and Hannah Toomey or John and Mary Toomey.
Gives me something more to ponder.
