Thank you very much Jan, Adrian, David and Winifred for all the helpful advice. I've been playing for about an hour now!! Just to clarify - I do have a photocopy of the marriage of Benjamin CROFT and Sarah BRIDGFORD registered in the Eccles PRs which have been filmed, and copies of which are held in Salford Local History Library. This marriage was confirmed by the archivist at the Central Library, St. Peter's Manchester, who checked the microfilmed copies of the BTs. This is as close as one can get to the original documents. So I'm pretty sure of the information if only IGI could be persuaded to accept it. Jan, I checked the three batch numbers and found one of them had a long list of entries of CROFTs born and married in Eccles at that time. So I need to take a trip up North to Manchester to search the filmed PRs and BTs myself. Although its a fair distance it's not as far as Australia! And I can look forward to a couple of days away... Thanks again. Ruth
