My 3x Great grandmother was Catherine Dewar, b. About 1815. in Newburgh, Daughter of David Dewar and Sophia Law.
She had a son, Henry Dewar, b. 21 12 1838, while the family were living in the hamlet of Muirhead (Kettle Parish). Henry's birth entry in the OPR says:
"Henry, nat. [natural] child of David Dewar, labourer, Muirhead [Kettle] and of Cath. Dewar also residing there"
"Natural" of course, means illegitimate. That's where the confusion comes in. Her father was, of course, called David Dewar, but she had a brother also called David Dewar, b. 6 8 1809 in Kilmany, so about six years Catherine's senior. I can't find any sign of David junior having died between 1809 and Henry's birth in 1838, and he isn't in the household, according to the 1841 census. The birth entry strongly suggests that Henry's father David must be a [close!] relative of Catherine's and Muirhead was a very small place. Was it incest, perhaps? David senior or junior the father? Or perhaps a cousin?
Looking at Henry's death certificate, (1923) no father is listed (!) but his mother is listed as "Catherine Dewar, afterwards (i.e. after Henry's birth) married to James Spark", and lo and behold, on the same OPR page as Henry's birth, 1843 sees the birth of Sophia Sparks, "daughter of James Sparks, labourer, and Cath. Dewar his wife" followed by Catherine Sparks in 1845, and James Sparks in 1851. James Spark(s) was 15 years older than Catherine, and also lived in the same tiny hamlet. I read through a year or two's Kirk Session minutes, expecting to see the pair (Catherine, and Henry's father David) of them "compeared" but either they didn't go to church (or they were too scared to!) as there's no mention of either of them, amongst the many names listed as being compeared for the sin of antenuptual fornication! I though for a bit the guilty party may have been her father, rather than her brother, but Henry's father was not listed as deceased, as is the norm, at his wedding to Isabella Sheath in 1860, and David senior died in 1859. On Henry's marriage certificate, Parents are listed as "David Dewar, General Labourer" and "Catherine Dewar, Maiden Name Sparks" - we know of course that her [later] married name was Sparks, not her maiden name, so a bit of economy with the real facts going on there, perhaps unsurprisingly.
Looking at some of the census entries for the family, Henry is listed as "Nephew" to David Dewar senior, but on David senior's death cert, Henry is the informant, and lists himself as "grandson", so definitely some more subterfuge going on!
Has anyone looked at this before, and come to a conclusion as to who Henry's father actually was?
