Hello David: Finden? Findon?You raise an interesting question.Today, many people assume my name is spelt FindOn, so I am sure the same varients spellings were used in past written records.For example, I have found a William Finden, married Arabella London, Ropley, Hants 31OCT,1736.William is variously listed as a Findon and Finden.(Arabella died in childbirth, and her infant son, William, died 10 days later - William, Senior was buried 9Mar, 1758 in Ropley -and may be the last of the Ropley Findens).
Norwegian families used to take the name of the family farm as a surnames."Finden" is Farm number 68 in Sogn, Norway, visit leegenealogy.com to see pictures of the Finden family. I can read Norwegian if you need translations.
I have not done any factual research on my Finden family, but have been in touch with Judy Finden in Australia and Tom Finden in Kent.It would seem that a generation-by-generation exploration may solve the mystery of Finden/Findon history, and I am willing to share my little knowledge and contribute time to a shared endeavours.
