Hi Barbara. Many thanks for your message. My ancestor Caroline Smedley (1820-aft 1861) m John Guyatt in 1846 was a sister of your ancestor, Eliza Smedley (1822-1865) who married Henry Braybrook Youldon in 1841, who I think was your 2 x great grandfather. I’m delighted to hear from you, and would be very grateful for any information about your family history that you are able to pass to me. If I can help you in any way please let me know. Possibly best is we communicate via my email address: geoff@geoffsgenealogy.co.uk.
