From Nona's obit which ran 2 Dec 1986, she was the daughter of Harry Merritt and Nona Williams. Born in Great Falls, Montana. She had two brother, which preceded her in death; Harry and John W Merritt. Obit states her husband died in 1974 and she is survived by nieces and nephews.
They are on the 1920 Great Falls, Cascade Co Montana federal census and by the 1930 census the family is in Wauwatosa, Milwaukee WI.
Though obit does not state so, she may have had a previous marriage prior to marrying Mr Sallenger. There is a death record for a female infant in Springfield, Sangamon Co IL in 1947 which lists the infants parents as Nona Merritt and Harvey Brand. In the 1950 Springfield City Directory is a listing for Harvey B and Nona Brand. If this is all one and the same lady, the marriage record may be under Sallenger to Brand instead of Sallenger to Merritt.
