Hi Percy veer. I have a Joseph McHolm in the 1841 census age 23 in Troqueer, others listed are James, Margaret and Neven. I have a death certificate for Nevin, father James McHolm, mother Margaret (nee Martin). I have other death certs of john,James,Robert with the same parents. That's why I've been looking for death certificate, just to confirm my theory. Oh yes, I'm on the hunt for William's death, born 1811. He could be another sibling!
