Hi Bruce - Many thanks for your research on this. I have all the Ronans (and their variations on name) - thanks to help from folk on here a while ago...
Think you might have found the marriage of John Shimmin and Mary Ronan...will pencil it in as possible.
Yes, I realised the IGI entry for Esther was submitted so not as reliable.
John and Mary Raunan had a female chr 3.6.1798 (too late if born that year to be included in Marjery's will in 1794). Also a son Thomas chr 7.12.1788 K.Rus.
Think Esther will have to remain a bit of a mystery...I still wonder if Marjery's will had the relationship right as neice before crossed out and replaced with grand-daughter...
Brian - will send the will and transcript to your e mail address on your website.
Thanks everyone for your interest and help in teasing this one out as far as it can possibly go. Liz
