There are no marriage records for Anna Margaret Saltsman and her sister Anna Maria Saltsman that I have found, if that's what you mean by "no sources". Their marriages are based on the baptism records of their children, and those baptism records are fully documented on my tree. If the record is in the Ancestry database, it will show up under Sources. If the record is not in the Ancestry database, I have listed the citation in the timeline, labeled Baptism or possibly Church Record.
The marriage of Werner Casselman to Rachel Davis/Davy is unproven. Even the name itself is made up, but I have accepted it as a sort of straw man, so that I can have a profile for the wife of Werner Casselmen to discuss with other researchers.
As for DNA, a Canadian research partner is a direct descendant of Werner's daughter Rachel and says she has zero Chrysler matches. Thinking about you this morning, I've added a couple of weblinks, found by my Canadian colleague, to my profile for Rachel - records that carry the names Neltie, Cornelia and Eleonora.

If you don't have an Ancestry subscription and can't open records I have attached to my profiles in Ancestry, you can contact me at [email deleted] and I will endeavor to give you more information.
The evidence for Werner Casselman's marriage remains unsatisfactory.
