Well, Phil, you've done me a great service here - not so much with baptism & marriage but death!!
Checking out FreeBMD Q4 1864 Uckfield drew a blank - because it was transcribed JOHN. Sent in a correction for that, and i'll order the certificate right away.
I've done a load more work on the Sussex Mews since my original post. Anyone wanting a detailed dialogue can contact me on paul AT dbnut DOT com.
Doorwoman: did you get what you wanted? I'm now 99% sure that (your) George & (my) Richard were brothers, sons of Thomas Mew & Sarah Pollard. George's marriage certificate to Hannah confirms father Thomas, Labourer. Can't lay my hands on Richard's marriage cert as he married in Australia.
BTW Phil, there may have been other children to George & Hannah - the "complete" list would run Thomas (1841), Louisa (1843), Jane (1845), George (1848), James (1850), William (1853), Benjamin (1856), Harriet (1859). EXCEPT the last 3 contradict my reading that mother Hannah died in 1852. Oh Dear! More certificates needed.
Paul
