I'm looking for information about their son David Brazil Plunk. I've heard that he is not their natural son, but that he and his sister, Gertrude, were abandoned by a family of "show people" passing through town and that Henry and Angeline took David and another family took Gertrude. Years later, David remembering a young sister, looked for a found Gertrude and that she did not even remember having had another family. Anyone with any info? Please email me.
