Old City - Galena Jonathon Brooks 1800-1859 is buried at Greenwood Cemetery in Galena, I'll The source you looked at on page 74 , April 1, 1857 lists in blue pencil ( New Yard) That is the opening of Greenwood and burials in the remaining pages of Alice Lawrason Barthells transcription of the sexton notes are in Greenwood.
I thought you might be interested to know that I identified the cemetery you photographed in Kansas. I learned that it is called Selig Cemetery, and the Deaton family I had hoped to find are buried there. I located an old inventory and added seven more names to those you found & photographed.
Census is mistaken...? Interestingly I just was looking in detail at each census, and in the 1930 census Hatti's husband is with one of their children and is listed as a widower, I found graves for he and Hatti in Liberal Seward County Kansas, USA
She is listed as passing in 1924 and he in 1942. So I don't know why the are both listed on the 1940 census when she had been passed for several years by then... perhaps he filled it out as though she was there... it's very odd! Thank you for your question, led me to dig differently and find out some stuff!
They are not twins. Hatti was born in May 1869 while Mary I have from the census as being born Nov 1872 (re 1900 census). Mary isn't on my bible as she's not my ancestor, however on the 1880 census you will find: David Oldfield, age 29 Olinda Oldfield, age 25 Hattie B Oldfield, age 1 in Union, Wayne, Iowa.
In the 1890 census you will find: David Olfield, age 39 Lurinda Olfield, age 35 Hattie B. Olfield, age 11 Mary Irrisha Olfield, age 7 Frank Olfield, age 4 in Canton, McPherson, Kansas
I can't find them on the 1890 census but the 1900 census Hatti B is married to Willis H Jones and she is 31 years old and she and her husband and children still live in Canton. I have Mary as being 26 and still living in her parent's home in Canton.
In the 1910 census I have Mary as being married to James S Coons and living with him and their son James, as well as her mother Orinda in Lakin, Kearny, Kansas.
The latest placement I can find on Hatti is she and her husband Willis are on the 1940 census in Phillipsburg, Phillips, Kansas. I have yet to find either of them on Find a Grave and am not sure exactly when and where they died though I expect Kansas as in 1940 they were 67 and 72.
