the greenia genealogy i have does indeed have david meldrum and mary greenia. i'm afraid it's not real complete, however. what i have for children is slightly different from what you list: i have william, walter, libbie (elizabeth?), louisa, cordelia, henry, david, and andrew. it looks like you might be listed; do you have siblings named james, berden, mary jane, kenet (should that be kenneth?), robert, and jack? if that's your family, you're actually listed as "junior." this genealogy was done by someone else over a number of years. we got hold of it 2 or 3 years ago. some of it is a bit sketchy, especially the more recent generations. it was given to me without documentation of sources, which troubles me, since it does go back quite far on pierre grenier's wife's side. mary greenia was indeed a child of peter greenia/greanya/grenier, jr., and a sister of noah greenia. will be happy to share what i have, if you're interested.
