I've added a genealogy of the Ingalls families to my website with 1670 people listed, most with the surname Ingalls. It is at:
http://www.dahoudek.com/LIW/ingalls/index.htmThe primary focus is/was on tracing the family ancestry of author Laura Ingalls Wilder but it took off in other directions as I wanted to trace related lines and those in geographical proximity to Laura's family (such as a Pepin, WI Ingalls family only distantly related to Laura). Emphasis is on those with the surname Ingalls, those some female (name-changed) lines are also traced. Biographical and census notes are included throughout. Ingalls relatives include a Civil War Union General, a US Senator, and the 20th president of the USA.
