I found a "Roberta Louise Sydenstricker, born 1918 in Iowa living in the household of Charles Ramsey, 1920 Iowa Census, Woodbury County, Sioux City.
Roberta later married a Andrew DeNoma.
Roberta may be the daughter of Florence Stowers and of course _____ Sydenstricker. Not sure just yet if Florence and Mr. Sydenstricker were married, got married or just had this child together.
Any thoughts on this Sydenstricker puzzle would be appreciated.
Thanks,
Daryl DeNomme
