What about this one?
1861, around the time Margaret was born:
John Brown, age 40. Miner. Born in Lanarkshire, living in Legbranock, Lanarkshire, which is in the Holytown registration district
Jane Brown, 32, born in Tyrone, Ireland
Children:
John age 16, Ann 10, Mary 4, William 3, Margaret 1, all born Bothwell/Holytown
Visitor: Mary Little, Visitor, 55 from Tyrone. She was a seamstress.
Now that last entry may mean that this Jane's MS was Little, but not necessarily
p.s. In fact it's isn't - I got ahead of myself and took a look, I really should know better. The birth that I think is for this Margaret Brown was on 03 April 1860, and the name of the mother had been Jean Viney. Jean/Jane is no problem, they are totally interchangeable, but I can't link Gillan to Viney, and I assume you looked at the original of the marriage certificate and are absolutely certain that 'Gillan' was what was written? Assuming you did, then this one is a no go as well unfortunately
p.p.s. In for a penny etc, so I just took a look at the marriage certificate to see if there was anything else.
Is this the one?
11 November 1881 at 2 Annfield Terrace, Partick
Margaret's address is given as 15 Grace Street, Partick, her huband's is 60 Castlebank Street, Partick
The witnesses are Agnes Carrick, presumably a relative of John's, and Mary Ann MClure, which may or may not help someone identify her., together with a Samuel Gray and a David Gray.
His parents are William Carrick, Ships Carpenter/Journeyman and Margaret Carrick MS Barlow. (not sure where the Rebecca is?)
I agree with you that Jane's MS is clearly written as Gillan, and can't have been mistranscribed from Viney.
Ah well, back to the drawingboard...
