Hi Julie, we are in LUCK!! I stayed up till 2am last night after posting my message to you and I think we found your answer!! You were looking for a Jean or Jane Agnew, well Williams parents were James Agnew and his mother was ......now i have 2 names listed so one might be a misspeling of a record but it all match's so....his mother IS Jean or Jane Drynan!! Does that match or help you in anyway? I also found this info on the 1841 Scotland Census,(I don't subcribe to the site so it only gave me the main info).
James Agnew, Age: 45, Head of family b.1796 Ayrshire,Scotland.Residence at that time: _?__?___?_,Ayrshire Jean Agnew,age:45, Wifeb. 1796 John Agnew,age:13, Sonb. 1828
I tried to search farther but it wouldn't give me any more info! So, if your related to these Agnews, Nice meeting you Cousin!please write me back! Thank you, Teresa
