In 1900 & 1910 Lily I. Brewer b. 1894 IL, was living with the Franklin Brewer family in Bond Co., IL. She shows to be niece. So checking out Franklin Brewer--he was son of Hasting/Hasten Brewer b. IL. He had several brothers, one of whom would have been Lily I's father and for some reason isn't around by 1900--. Probably died as did her mother ? Finding her birth certificate would be your best bet--and Bond Co. IL is probably where to look. Franklin's brothers all b. IL were:John W.b.1848, Francis Marion b. 1856, William b. 1858, George b. 1861 and Thomas b. 1863.
By 1920 she was m. to Roy Fred Lindley and living in Grant County WA
