Looking for any information on my great-great-grandparents, Alfred and Sarah Margaret CHIPPS BROWNFIELD, and her brother, John CHIPPS, who apparently settled somewhere in Delaware Co., Iowa, in later half of 1860's. They returned to Pennsylvania by 1871 (or perhaps even sooner). There may have been relatives in Delaware Co., and they may have received an inheritance which brought them there. Alfred BROWNFIELD born 1844, Sarah Margaret CHIPPS BROWNFIELD born 1845, and John CHIPPS born 1845. Any information, including deed or tax records, is most appreciated. Thank you!
