dear mr clark, I just wanted to thank you for your very generous information regarding your ancestor. I have an Archibald Sydserff book "My Erasmus" which one of the many of that name used for their study, and wondered if you would like to have it? If you leave your contactable email or address at one my inboxes: staggerlee2009@googlemail.com you can leave directions for its postage. It has many signatures in it and is very old. Once again, many thanks, charles sydserff.
