Sarah Creber married Robert Stewart in Scotland in 1878.
In 1891, the household is in Ardrossan, Ayrshire.
Her father is Henry Creber, aged 75, born in England, retired contractor.
Scottish death certificates give people's parents' names.
Lewtrenchard and Buckland Monachorum, Devon, where the family I have referred to lived, form a roughly equilateral triangle with North Hill, Cornwall, about 10 miles on each side, with Launceston between North Hill and Lewtrenchard. I don't think I would be surprised to see North Hill, part of the area around Launceston that comprises the border between Cornwall and Devon, referred to as being in Devon by the daughter (the informant?) of someone who died in Scotland 75+ years later, especially someone whose family may well have settled in Devon not long after he was born, and who then married and had children in various other places. I would also not be surprised if the person's mother's name was mistaken. Of course, the death certificate should also state the mother's surname, if the death was in Scotland, or New South Wales, or Ontario ...
That Henry Creber died in 1891 in Scotland, I believe. In 1881 he is shown at Anc'y as Henry Crebar, born in England about 1816, in Barrhead, Renfrewshire. He and his son-in-law Robert Bromfield Stewart are both contractors. In 1851, the family may be in Finchley, recorded as Crever, Henry's place of birth given only as Devon. That Henry married Jane Titchener in Berkshire in 1841.
Am I getting warm?
