Notes:
Nothing can be discovered or known about Chester other than he is listed as the father on Donald Eugene Mumma's baptismal record. Mother as Carrie Grimes, unmarried. There is a strong suspicion that the name "Chester Mumma" is fictitious. A Y-DNA test by his great grandson showed that the grandson does not carry the MUMMA surname Y-chromosome.
