Lydia may have had three children by William F Stork (1875-1924), Lester (abt 1910-?), Ethel (abt 1914-?), and Evelyn (1923-1924). The 1930 US Census shows Lydia living with her stepson Oliver, William's by Anna Lindner (1879-1916), and her son(?) Lester (b. abt 1910 or 1912) and daughter(?) Ethel (b. abt 1914 or 1920). Both of the latter are shown with surname Kuehnert.
First, how is it that Lester and Ethel have the surname Kuehnert?
Second, how is it that Lester and Ethel were born before Anna's death?
If I assume these were all upstanding people, then I must conclude that Lydia was married to a Kuehnert before marrying William and the children's surnames were incorrect in the 1920 Census for William and Lydia. Does anyone have evidence of what the actual situation is?
