Many thanks Liz.
Yes, it is from the will of Marjery.
I have found the death of Esther Corkish on Lawson's CORKISH, Esther age 49 Kirk Rushen 19 Sep 1835 .
This puts her year of birth at about 1786 - if it's the right one, which I think it is. Someone from Fam. Tree Forum has found what looks like her widowed husband on the 1841 census.
Think that is as far as can go with this - at least proved Esther is the daughter of Mary, daughter of Marjery. Think it is a fairly safe deduction that Mary was called Moll(e)y in the will.
No other daughters recorded on IGI to Marjery.
Thanks again. Liz
