Wow, thanks Elaine and also Kite. Yes, Boston Spa is really part of Wetherby. I think this must be her marriage. Will go and look. I really must now renew my subscription to Ancestry and get stuck in! Thank you both of you.:)

Had a look and yes, sure it's her. Will now get the certificate. Thank you both so much.:)
