Your Bridget cannot be the one. My 3x grt grandfather was born in 1816, so I am estimating his mother, Catherine's, birthdate. The information I have for her is correct, as I took it off of his death certificate. I do not know if Laurence is the oldest child, though, so the hunt goes on! I know that William Ryan, her husband lived in the Nenaugh region.
Thank you so much for checking on this; I am so stumped! Beth
