Checked the LDS site, found 3 wives listed for Frederick, as follows: Mary Linderman, (2ed Wife) Hester Reifsnyder Whortman, (widow) Elizabeth Nagel. No children are listed for either. Obviously the last two are inverted. I did a quick search for Mary Linderman and could find nothing on her. I suspect that if she did marry Frederick, She must have died very soon afterward.
It would appear from her name that Hester was probably married before also.
