Yes, am in Australia - so can supply much more info on the Smiths after they arrived here, but would love to find more earlier info. All I know is that Isabella married George Smith 15 Oct 1845 in Worcester St. Martin. Have not yet found what children they had, but believe it was their son, George, who came to Oz.
Would love any more info on the Smiths that you may have! I have fairly good details for Smiths from 1879 on - so you can see, I do have quite a gap.
I noticed in your summary of James Baldwin, you mentioned a child, George. I had not found him before, so will add him to the family. I also noticed that you missed Henry - he was born in Bretforton in 1821 died and buried there in Mar 1836.
You might also like to add to your info that Anne Potter was also in the Army in Meerut India when they were married (probably a nurse). I am certain of this as I have their original marriage certificate.
