Hi Nell,
I know that Adam Kellock married Ann on 27 Feb 1827 from his R A Service Records. I originally thought they may have married in Woolwich but I haven't found any record there. So, as two of their daughters were baptised at St Thomas, I thought I'd give that a go.
This is definitely not the Adam Kellock you mentioned, as mine died in 1847 on Corfu.
Thanks anyway. He's a very elusive chap this one!
