Yes, mea culpa, I meant Old ChArlton, but it's easy to do a typo like Roslyn instead of RosAlyn!!
Thank you anyway for all your help & for directing me for sure to St Luke's as I wasn't sure if it was St Thomas's.
I'll contact Greenwich & see what they have to say, otherwise I guess I have to fork out another 9pounds 25p. This family tree business certainly eats up the cash!
Actually you say the marr cert will be identical to the one they photocopy, but over the years, especially before they went on line, I've had 2 marr certs copied incorrectly & gone on a wild goose chase for a name that didn't exist, due again to someone not reading the original carefully enough. It's easy to do as you can see. So I'll much prefer a photocopy!
Thanks again for your help, much appreciated advice.
