Hi: Have not found much, but have learned there is a Peck, KS History, published about 1887. There is some information about the ROLL family in it. Hopefully, someone will send me the information. Doesn't look like Sumner Co has a Hist Soc or Gen Soc. Have you posted anything on Genweb for Sumner Co? If not you might want to try that. If your Roll's are not part of the Dutch line who go to Kansas, they are probably German and probably came in the late 1800's. Just would have to find the point of entry. Good luck, will keep in touch. Nancy
