Thank you Roger. Your quick reply is a great way to start the new year!
I only have her death certificate in 1871 which lists her parents so obviously one of her children provided the information. I have double checked the details and I have to apologise - for some reason I have 'Margaret' on the brain - the certificate actually lists the mother's name as Bridget O'Neil.
She was aged 60. If so, then born about 1810 so about 23 when she married. Interestingly both witnesses were military. One of whom was John Neil. That may have been coincidental. I have searched his military records and found he was born in Borris - possibly a relative?? (I have found what is probably his baptismal record in 1812 at
Borris to Arty Neil.) It may be therefore that she didn't come from Carlow despite being married there.
There seems to be a tradition in Australia that people added an O to the surname as that came to be the accepted spelling. So it is possible she may have been plain Neil originally. (That certainly happened on my father's side with one great grandmother progressing from Hare to O'Hare and then changes in spelling of 'Hare' followed.)
Her youngest child was also called Bridget. All were born in Australia.
Again, thank you for your help. I don't know if the extra information warrants a second look. I am hoping when I get over to Ireland in a year or two I will drop in at Carlow.
Regards
Mary
