Hello I have come across Arthur James Gwatkin in my tree.
I had Mary Ann Monk down as Mary Ann Plant and am getting confused. Perhaps she was married twice? Her mother seems to appear in some of the census returns. If you have more information I would be interested. Didn't know that part of Gwatkin family worked for the railways. Most of my Gwatkin family come from Bishopswood, Walford, Goodrich, Ross on Wye.
