For Richard Lloyd and his wife Elizabeth (the ones I am most interested in) I have nothing at all, but for John Edwards (who married Richard's sister Eliza) I have his occupation at the time of their marriage as 'Carpenter'.
I don't believe that any of them had children whilst still in UK.
Richard and Elizabeth had a son (Henry David - my gr grandfather) in 1843 soon after settling in NZ, but I have found nothing about other children of theirs. (However, Henry David's children were Henry William, Charles Herbert, Richard John, Owan (or Owain), and Hubert.)
John and Eliza's children were Thomas, John, Edward, Charles, Sarah Anne, and Robert David.
I apologise for my ignorance!
