David,
Here’s Alexander’s birth cert. he was born in Largymore outside Lisburn:

Parents marriage in 1869:

They had son William born 19.2.1872 in Largymore. The family appear to have moved to Ayrshire after that. Cecilia was born in Dalrymple in 1874. Samuel & Eliza both die din Ayrshire (1924 & 1913 respectively). It doesn’t look as though anyone remained in Ireland save for Samuel’s parents and any siblings he may have had.
At least 1 tree on Ancestry (The Wilson family) has this Rosann Hawthorn as Samuel’s mother. She died in 1872 aged 60.

However that same tree has Samuel’s father William dying in Lisburn in 1896. But if Rosann was his wife, she was a widow in 1872, and so he pre-deceased her. That Ancestry tree does not therefore appear to be completely accurate.
Same tree on Ancestry lists 3 possible brothers for Samuel. Thomas? b 1861, Robert 1862 – 1936 and John (no dates). Robert also appears to have headed for Scotland. He died in Glasgow in 1936. No information on the other two brothers.
