For all their married life, Joshua and Lily Wellcomb lived in a small town in Kansas, where they just managed to feed themselves and their three children. In 1888, Joshua died from influenza, leaving Lily with three children to look after. The family was left with very little money, so when the Oklahoma Land Run was announced in March, Lily had a difficult decision to make. She thought about it for a long time, then she sat her children down at the kitchen table in their tiny house.
