This is wonderful! Real documentary proof at last that my mum’s story was right! Thank you so much.
Irish records, especially for that early period, are woefully patchy. I even approached a local Donaghcloney researcher some years ago to help me find a record of James Alderdice’s marriage but, as she said, very few records survive and those that do rarely give a wife’s maiden name.
I trace my line from your William’s younger brother Samuel who was christened in Donaghcloney Co. Down on May 4 1838. Samuel came over to England (Lancashire) at some point between 1861 and 1866.
He married a Mary Boyle (also from Ireland) in the February of 1866. The marriage certificate states that his father, James Alderdice, was a Groom. My Donaghcloney researcher suggested that this must mean that James had been employed on one of the local Estates.
Samuel was a Commercial Clerk at the time of his marriage. Three years later his daughter, Margaret Alderdice, was born. She married a Robert Hope in 1890 and they are my Great Grandparents their eldest daughter, Florence, being my Grandma.
I would love to know anything else you have found out about William (who he married, when he emigrated etc). Before reading your posting on Genforum I had wondered whether he was the William who married Rachael Kathleen Monroe in 1871. [Rachel and their son Frederick ended up in Newfoundland but there was no trace of William there.] Clearly, unless he married again, that is not the case!
