My great-grandfather was a William Stocks who was b. 1857 in Welwick which is not far from Hull. I did some research myself in Yorkshire last summer and found that there is no record of the Stocks in Welwick other than him, so the family had to have come from somewhere else around there. My William moved to Withernsea, married and was in London by 1881. Do you think there is a chance that your Edward and my William were brothers? Of course you did not say how old your Edward was in 1881, there is a possibility that his father was my William's brother. There are lots of Edwards and Williams in my branch. Would be pleased to hear what you think. My branch of the Stocks still mainly live in London, except for me (in Sacramento, California).
