Three years after the birth (and death) of her illegitimate child Margaret Bruce married Thomas Higgins in 1874. It was hoped that the marriage record would help identify Margaret’s father but instead it throws a few red herrings into the problem of who was Mary Mathieson’s partner and William and Margaret Henry’s father. Margaret Henry/Hendry/Bruce gave her father as James Bruce, gasworks labourer, dec'd, and her mother as Mary Bruce, ms Hendrie. I believe her father’s name to be erroneous and her mother’s only approximately correct. Perhaps this 21 year old illiterate was ignorant of her father’s identity and/or fictionalised information for her own reasons, though her father’s occupation may be accurate? I cannot find anyone called James Bruce in the area in the 1851 Census but one one of the possible candidates for her father - William Henry - was working as a labourer in a gas-works around this time. When Margaret Higgins died in Airdrie in the parish of New Monkland her son, John Higgins, reported that her mother was Mary Mathieson, subsequently married to Alexander Crichton. No father was given. There was certainly a lot of uncertainty around this time as whether Mary Mathieson’s illegitimate offspring should use the surname Hendry or Bruce and 'Bruce Hendrie' increasingly appears. Margaret’s brother William Hendry gradually changed his name from Henry to Hendry to Bruce Hendrie and eventually Bruce. So where was William Hendry/Bruce?
