Lucius King 1937-1921, born in Ohio, who were his parents?
Alonzo L. King his son, 1879-1963(?) where he die, wife Gertrude (maiden name?) what happened to her?

Lucius King listed 1910 Indiana Census for Wells County with Alonzo. 1920 Lucius listed in Grant County at the National military Home that was there. Suggest you try genweb site for those two counties for further information. If it is your Lucius at national Military Home there should be a military record and possibly pension record at the National Archives. Pension record would give a tremendous amount of information.
Best source of information in Grant County is the Marion Public Library. Contact them at their website.
