I am doing a search about Gavin Black (my 3 x GG) and a sasine from 1777 and whether a Gavin Black of Rawyards depicted in a painting on curling is also the Gavin I am looking for, I would appreciate any information to help me with finding some of my family history from Scotland
I don't think it can be the same person, but he is definitely related.
The date of that painting is not precisely known, but it has to be around the middle of the 19th century (1850s/1860s). The Gavin Black in the painting is almost certainly the one born in 1800 or 1802 and died in 1871.
The one to whom the 1777 sasine relates is almost certainly the grandfather of the one in the painting. He was born in 1732 at Rawyards and (according to the sasines) died between 1803 and 1806.
What I don't know is how, or even whether, Gavin Black of Craignook relates to the four Gavin Blacks of Rawyards who succeeded one another, father to son, in Rawyards from about the 1740s until 1871. The first Gavin Black of Rawyards was born in 1704 and married Mary Wotherspoon in 1727 and they had nine children between then and 1749. The first Gavin Black of Craigneuk married Bethia Cullen in 1734. The Registers of Sasines mention four children of Gavin Black of Craigneuk: John, William, Bethia and Isobel, but I do not have reliable dates of birth for these children. However the Craigneuk family must have been roughly contemporary with the Rawyards family, so Gavin B of Craigneuk can't be the same person as Gavin B of Rawyards.
