BonnieJean on Family Tree Circles

I have been researching my father's family for five years. I believe strongly that he was born to Samuel Blackmore and Susannah Snell shortly after they married and moved to Dublin during the exodus of the Sailing Trawler fleet from Brixham, Devon. Samuel and Susannah had a son named George who died shortly after he was born. My great-grandfather would have been born in between this still birth and the birth of Samuel. There are several trees that show George1 without any other information showing born 1849, d 1928. This could be my great-grandfather however there are no records in either Brixham or Dublin showing his birth. My father is 99 years old and will be 100 in November. I want so very much to give him his heritage before he exits the planet. Can anyone help me out??? Thanks! Bonnie Jean
