Have recently read your message on the Allan family of Darlington, since your message is a little over a year ago, I am not sure how much you have updated your information. I am the paternal Grand-daughter of James Appleton Allan, Great grand-daughter of James Wm Allan & Annie McFadyen.
I am not sure where the Appleton middle name came from but James's uncle is also a John Appleton Allan. his Mother being Ellen Thompson (mn).
Would be interested to hear more on the McFadyen family.
