Haven't checked the death records yet.

City directories show the same Bostic(k)s from 1920-1929,
with wives named Ida, Louisa, Liilian, May, and Ruth.
The last few years, there was also an Earl with no wife listed.
(I think he was a military recruiter, but it wasn't clear)

Some years did not have a county (non-city) section,
but in the ones that did, there was a "Wm D... (Marion)"
