Was he married twice? Was he divorced at some point? To Anna Mary (Newell) Lockling. Children Lina B. Lockling & Ruth Lockling & I thought they were the only 2 they had together.
Married to Sarah Starwell. Son Herbert Eugene Lockling & I thought Sarah & Francis were theirs!
But on a 1910 census the children listed for Jackson & Anna Mary are all the children, Lina B. born Lockling, Ruth Evangeline, (born Locklin) Messner, Herbert E. born Lockling, Sarah L. born Locklin, & Florence M. Lockling.
Maybe whoever made the entry forgot the "g" in the last name for a couple of the children.
