Hi all
Thanks for the kind comments - really down to the Google Finger- it has a life of it's own, I think!

Musing on the possible 1841 for John which Monica found in Gorbals
In 1851 Gorbals is:
Lodger: Janet ANDERSON b Ireland, age 22, Seamptress
(In household of Sarah Stockdale who has a son William age 25)
Also 1851 Gorbals in another household is:
Visitor: Peter WILSON 36, b Cardross Dumbartonshire, Merchant Grocer
MARRIAGE in Gorbals 13 April 1851 (just after the Census)
Peter WILSON & Janet Renwick ANDERSON
(There is a Janet R ANDERSON in Barony too, in 1851 - who may be Peter's soon to be wife. But ....I'm sort of hoping she's not).
BIRTH:
Janet Anderson WILSON
chr 27 Jun 1852 - Saint Enochs Free Church, Glasgow, Lanark,
Parents : Janet ANDERSON & Peter WILSON
In 1861, Peter WILSON is in Eastwood Renfrewshire, with his daughter Janet Anderson WILSON age 8 b Lanarkshire. But he has a new wife Christiana (TOWIE I think, m 1861) so his first wife Janet must have died? He also has servants and seems fairly well-off
I'm harking back to Margaret Maxwell ANDERSON being described as the 3rd surviving daughter of John.
Whilst this stmt could be in error, if taken as fact it indicates there were 2 living sisters older than her, and at least one who died. And although Margaret was only the 2nd daughter of John with wife Janet - he could have had other daughters with wife-nr-1.
Monica, I wondered if there could be a marriage announcement in the Glasgow Herald regarding the 1851 Marriage in Gorbals?
Cheers
