Ihave the following on Haswell and Elvira. This is not my husbands direct line but I keep notes on other Pinneo's I find.
Elvira was the daughter of Wilber Warren. Two children: Albert born 1838 in Scott County and Martha born 1842 in Scott County. Haswell died in 1848 and Elvira married Alexander Kennedy in 1850, he was born in 1806 in Penn.
The following I believe was from the History of Scott County, Page 629 or 631. Haswell came to Pleasant Vally Township, Ia. 1835 with other members of his family. He enlisted in Lincolns Troops in The Black Hawk War and was in active service thru out the war. If I find more will send direct. Good luck, Edna Pinneo
