Thanks for the info. Since I posted this query we have found much info on Rachael. The Thomas Prall you found in the 1880 census is Rachael (Prall) Orrill's older brother. His wife's name was also Rachael. The Pralls were both born in IN, some of the children of Cornelius Prall and Lydia Van Syoc. She married Winfield S. Orrill in 1871. He died in 1873 in Fairfield, IO and she later married Nathaniel Gilbert Page. Rachael (Prall) Page died in early 1880 in IN. She left one son from her first marriage (my wife's great grandfather) Artemis Hazen Orrill who with his half brother & sister went to live with his aunt and uncle, Thomas & Rachael Prall in IO, in the early 1880's.
