Hi, I am throwing myself into this research too and wondered you guys had turned up anything. After cross-referencing ancestry, fibis, and family search I ended up wanting to delete everying before the marriage of CHarles John Bennett and Anna Jordan, because working backwards that was my last best known good configuration - lol.
There are a couple questions. If Jane McCay was born in 1811 and was already a widow when she married John Bennet in 1825 she would have been 14 and already widowed. There is another Jane and John Bennet wedding listed too which had me confused. I think in the second case the Jane was born in England. I see a death for one Charles in India and another later in Scotland.
I am at w i l d l o r at g m a i l dot com if either of you want to talk off the web stream. Also am online via my D'Fini tree (Millicent Clarissa Bennet (daughter of Charles John Bennett and Ellen Grace Goultchman Clarke was my mom's grandmother)) She married into the Finch family.
Name: Charles Bennett
Gender: Male
Marriage Date: 18 Jul 1825
Marriage Place: Poonamallee, Madras, India
Spouse: Jane Mcclay
Her death record shows 1811 as approx birth year.
The second marriage I was confused by is:
NAME: Charles Bennett
GENDER: Male
MARRIAGE DATE: 31 May 1825
MARRIAGE PLACE: Calcutta, Bengal, India
SPOUSE: Jane Lumsdeine Or Lumsdaine
FHL FILM NUMBER: 498955
HOUSEHOLD MEMBERS
NAME
Charles Bennett
Jane Lumsdeine Or Lumsdaine
marriages two months apart both Charles's and Jane's
Interestingly Jane had a sister Francis and both married Bennetts about four years apart (probably brothers, both in Calcutta - John and Charles Bennett). Their birth years make more sense but I don't have enough family history to know which Jane and Bennett combo are "my"pair.
I think it is the Madras Charles and Jane McClay - so I am probably in the same lane as you are Normalynne. I'll keep plugging away
