Oh my,
I am on that site now, but I've got 225 pages of Tarletons, so shall be busy for days I'd think ?
The IGI Ancestral file does have George Ms marriage to Louisa Best in 1819, which gives me her parents names and birthplace as Chilson Park, Kent, but I have the actual image from Ancestry, which shows born Ireland . Also ( maybe an error ?) the header for George shows christening and is his marriage ? But it has given me a little bit more info.
They had 5 children from what I can make out , our Weldon C, being eldest, Thomas and George born abt 1826 , Dora abt 1831 and Barbara 1833. I have found them in 1841 , 51 and 71, but as George M was an Army Captain they did move about all over the place. No sign of where the twins were born , Dora born France, Barbara born Bangor, Wales. Louisa died 41-51 not known where . Thomas and George are missing apart from the 41.
P erhaps I might find more on the next 220 pages I have to go through

It will keep me out of mischief for a bit. I did guess it would be Parish records for the period I'm after.
Many thanks again,
Lyn
