Many thanks for your offer of help, the reason that I have ordered Clara's birth certificate was that I got totally confused by the 1881 census I am pretty sure that Clara's father is down as Arthur J Sawyer as the rest of the details do line up it states that he was married to a Elizabeth Cooper and that Arthur the son in the 1891 census was in fact her son Arthur E Cooper, Walter the son on the 1891 census also turns up on the 1891 age 5 months which lines up Do you think I am correct
