William strachan is also my 4th great grandfather!
We must be related in some way.
I was wondering how much information you have on them?
I have lots of paper work and photos of the whole strachan family.
Do you know how they became so rich?
How far have you traced them back?
I also have the cavill's family photo album dating from around the mid/late 18th and early 19th century. It includes Isabella Strachan who is the mother of Frederick cavill the famous swimmer.
Would be nice to hear from you.
P.s attached photo is a painting of Richard John strachan. (Isabella Strachan's Brother) Painted around 1840 at Seven kings Romford (dark photo)
The other attached photo (man with medals) is Frederick cavill. Taken from the family album.
