OK, I am doing a favour for my godfather, who would like to find out about his grandfather. I am pretty stuck, so I would be grateful for any suggestions.
I have a birth cert. for Thomas Boylan, born 21st May 1898 in Blackfriars.
Father is James Boylan (a mason), batchelor, mother is Sarah Boylan (née McLachlan / McLaughlan)
I also have found the marriage certificate for them on 6th Jan 1897, both residing in 12 North Street, Glasgow. Sarah was a book folder, her parents were James McLaughlan (deceased) and Margaret McLaughlan. James's parents were Lawrence Boylan, a mason, and Charlotte Boylan (née Brown).
I have found Thomas Boylan, living with his mother in the 1901 census at 30 Taylor Street. But no sign of the father.
I found Sarah (b. 1864) living with her mother in 1891 at 114 Trongate.
What I've not managed to do is find any sign of James Boylan on a census. My godfather says that his father never spoke about his father, or of any relatives on that side of the family, though he believes that he was born in Ireland.
Has anyone got any suggestions on where I could look for more information? Are there immigration records from Ireland to Scotland at this time? Where is James Boylan, before and after the birth of his son?
