Am trying to find info on location and date of birth for the 10 siblings of Daniel and Emily Houghton Curtis. Believe all to be born in Bloomington or Normal, IL, probably between 1850-1870. Census for 1860, 1870, might show this. Ten siblings are: David, Marion Francis*, Minerva Curtis Green, Rovilla Curtis Denton, Lou Curtis Jones, Arthur Curtis, Addie, Marie Curtis Robbins, Violet Curtis Ganson and Alyce. * Believe Marion Francis Curtis was born in Bloomington or Normal in 1860. Also if available, would like census info on Charles Ganson. I know he and Violet were living at 106 W. Cherry in Normal from pre 1920 to sometime in the late 1930's. This my first venture into trying to find info on my ancestors. If I am not proceeding in the correct manner, please advise how I should proceed. Thanks. Bob Curtis Bradenton, FL
