Robyn, Thank you for the list of children, we have ordered a birth cert for Albert b. 1873 which could tell us his parents place of birth ?? and occ of his father. As you say there is no registration of a marriage of William Horton to Eliz.A. Royston so we are thinking they may have married elswhere, NSW or UK or may not have married at all. We are going to have a look at what we can see in the NSW records if there are any to look at on line. Thank you for your help and time, it is appreciated, and eventually we will see if that William and Sarah Campbell are in the family.
