I have just started looking at this line.My Gr-Grandmother was Lula Mae Peck.She died when my Grandfather was 12 yrs old and he was an only child. No one knew anything about Lula Mae's family. I found her on the 1900 census in the Indian Territory, Cherokee Nation, Okla.Her Mother Mary was born in IL as was Mary's Parents.So I Looked and found a Marriage License for her and her husband Amos Henry Peck.I found Mary's Parents on the 1880 census in Sumner Co. Kansas as E.A. & D.C Herrelson. The place of birth for the children were IL, KS, and Indian Territory and I am asuming this is OK. My father and grandfather were both born in Okla. and Lula Mae was born in KS and buried in Bartlesville, OK.
I have a picture of Lula Mae and her sister Maggie Peck Shipley and Maggie's son Floyd and my Grandfather Edwin Ellsworth Knisley.This is all I have to go on. I have such little information on this line that I have been putting off doing much in the way of research. When I saw your post it looks like a possible match.
