Tilghman Peter

Tilghman Peter was born Oct 1 1835 which probably comes from a book by Beulah Klotz about the Peter family.  He is the son of Nicholas and Salome.  Did he marry Rosa Heintzelman?  Is his daughter Ellamanda L. Peter born Nov 22 1876 in PA?  I have another Tilghman Peter b Oct 1 1855 married to Rosa with the same daughter.  This Tilghman is the son of Jacob and Maria.  I need help figuring this out.  I think the second set of information is right, but need more documentation.
