Hello Gregg
Maybe you should wait for the Meldorf records to be done by the LDS (this
year according to a lister) then find the marriage of the parents of those
children you have; probably a year or so earlier. The marriage will give you
the names of their parents
(the grandparents of the siblings you have the births /baptisms of). I
suppose you realise this anyway, but it helps sometimes to have someone else
reinforce what you already know. Anyway Good Luck with your research.
Gene.
