Thank You, Newf and GeoffE for all your help. I will have a good look at the info. Dont think William was adopted he was married in his birth name. His marriage details are William Henry Clark. Bourn 7a 579 Ann Speed Bourn 7a 439. Married March 1876. dob William 1852. Ann 1856. As the William you found was a farmers boy he could be the one, possibly learned to ride on the farm as later he became a Horseman on the railways. Will have to see if I can get a marriage certificate that will possibly help. Thanks again, Appreciated.
