I managed to visit the Mitchell Library today. I found Margaret Wilkie's poor relief record. I found a Robert Williams from Londonderry, Ireland just like mine but it wasn't the right person (ie occupation and age didn't fit).
I'm still nonplussed. Here are the relevant details:
Margaret (age 44) on 15/11/1906 when the poor inspector visited her. No details are given about Robert's parents, he is simply described as her "paramour" (illicit lover). It states that he died 5 months ago in the Royal Infirmary. Thing is, I cannot find a Robert Williams who died in 1906 aged around 44-45.
It states:
"Applied for outdoor relief because her paramour has died. She was previously supported by her paramour's efforts".
It then rhymes off all of the illegitimate children they had together, noting that Robert Williams, a rigger, was the "putative father".
It then states:
"All children registered by putative father except for one, Robert. Reason for this one exception is because putative father (Robert Williams) was away on a long voyage at the time (1885)."
There is some confusion about the religion. Margaret is wrongly put down as a Roman Catholic, it is then corrected to note that she is actually Protestant. However it says that her children were all Roman Catholics. Can I presume that this means Robert was a Catholic? His daughter, my great-great grandfather, was definitely a Protestant since she married in the Church of Scotland. This, therefore, confuses me as well.
So I'm not sure still where I stand. I was hoping for some details on Robert's parentage. He is such an elusive person! Either Margaret knew next to nothing about him or she was purposefully concealing information.
I will go back to the Mitchell and look up some of the children when time allows but I'm not holding my breath that they will know anything much else about their father.
