Goodness! So many name variations to pick from. Delarosbil and Dunys (and their different spellings) do not appear in the Acadians Project Standardized surnames list, and do not have entries in the Dictionnaire généalogique des familles acadiennes. Dunys does not appear related to the Nicolas Denys line. More research is needed to clear up uncertainties concerning the Dunys/Dunis/Denis lineage and name. In the meantime, could you set the duplicates of Marie Denis as an unmerged match?
As for Delarosbil, PRDH uses that standardized name. Since he does not seem to have Acadian ancestors and is outside the Acadians Project parameters, (married likely after 1763, outside Acadie) maybe the Québécois Project team would have recommendations?
