Poor Helen Stobie.
Comfirming her marriage in Peebles will connect her to the town.
There are hardly any Hamiltons in the whole of Peebleshire at the time of 1841 Census. In fact according to Freecen there are 33 adults and children, and most of the adults were not born in the County.
The evidence connecting Helen Hamilton to Jane Hamilton is
1. They both give place of birth as Dumfriesshire.
2 Helen marrys in Peebles where there are very few Hamiltons in residence.
3. Helen's daughter is called Ann (mother's mother
)
4. Helen has a 2 year old Ann Ferguson with her on 1841 Census
As Millmoor says unfortunately you may never prove for certain that the women were sisters but I think there is a very good likelihood that they are connected.
to find the Stobie's marriage in OLD PARISH RECORDS on Scotlands People search Stobie John -Peebles Peebleshire and/or Stobie John -Lasswade Midlothian.
Also 1851 Census - Scotlands People has a Jane Ferguson age 50 with second person forename Anne at Balmaghie Kircudbrightshire
. You should be able to view the image.
Someone must have been financially supporting Jane at this time ( family members) if she was not working. I'm not sure about the possibilty of living off her husbands estate
for ten/twenty years.
I still think William was dead pre 1841 (if he was married to Jane) and she is a widow at the time of that Census. William could have died in Peebles or Midlothian or anywhere.
