Brilliant - thank you! I thought I'd checked other churches, but I must have limited it to Glasgow - lesson learned
I suspected there'd be an Elizabeth, and her middle name is extremely helpful indeed
Once we go back to Duns the records are a little patchy, but Matthew's possible paternal grandparents were either:
a) Matthew Forbes & Wilhelmina Hately who married in Coldstream in 1764, baptised a daughter (Ann) in Edinburgh in 1765 & then vanish - OR -
b) Matthew Forbes & Janet Henderson who are noted in the 1774 Kirk records in Longformacus:
"11 Dec 1774 To Mathew Forbes in the parish of Edrom & Janet Henderson in this parish matrimonially contracted - 1 shilling" CH2/250/3, image 303
Both Matthew's were tailors, or perhaps they were the same man - this is what I've been struggling to piece together. I have:
1793 Duns
Matthew Forbes s/o William Forbes & Elizabeth Walkingshaw. The witness names were James Walkingshaw & John Ford, although it appears to have been written up some years later as the page is headed 1807 and the entries jump around from 1790's to early 1800's
1795 Duns
James Forbes s/o William Forbes & Elizabeth Walkingshaw. The page is again headed 1807, same scattered dates, and the same witnesses.
1799 Duns - burial of Elizabeth Walkinshaw wife of William Forbes, tailor of Duns, aged 48
1800 Duns - marriage of
William Forbes tailor of Duns & Janet Anderson of Highlaw. Witnesses were James Walkenshaw & John Anderson. Same marriage noted 2 weeks earlier in Edrom but with no witness details. Janet died January 1840 aged 74, so born c1766.
1801 Duns
John Forbes s/o William Forbes & Janet Anderson. This is written immediately after the 1795 baptism of James, with the same witnesses.
Their other children were Janet 1805 & Wilhelmina ("William Mina") 1808.
1804 Duns - marriage of Thomas Wilson of Broomhouse &
Jean Forbes d/o Matthew Forbes tailor of Duns. Wits
William Forbes & Mary White. Jean died in 1838, aged 56, so born c1782.
1809 Coldingham/Coldstream - irregular marriage of John Ford of Coldingham and
Isobel Forbes d/o Matthew Forbes tailor of Duns. Married at Coldstream, confirmed at Coldingham. No further trace after this.
My 4x Great Grandmother was
Wilhelmina Forbes d/o Matthew Forbes, tailor , born in Duns around 1780. Although I can't find a baptism or a marriage for her, the baptisms of her children confirm she was native of Duns & that her father was Matthew Forbes, tailor. She died in 1832.
The 1841 census for Duns has:
William Forbes 66 tailor
John Forbes 41 tailor
Wilhelmina Forbes 13 - she was the illegitimate d/o Janet born 1805.
ADDED: William died in 1845, aged 70.
