There was a J. S. Naylor who was born in Wisconsin. His wife was Carolyn Cave, and they had moved to Decatur County, Iowa by 1880 when his son Mervin Leroy Naylor was born. Mervin married Mary Frances Silkett and they had a son, Laurence Leroy Naylor. Laurence was born in Decatur County, Iowa in 1928. The family was still there in 1940, so there is a good chance that other family members might be in or near that area.
