Fred Stevers Irene's headstone is located directly behind (west of) the Stevers family headstone that has the names of Martin, Sarah and Arthur. According to her headstone, she was born on May 31, 1897 and died on September 21, 1900 at age 3. I searched for her obituary in the Chicago Tribune archives, but unfortunately couldn't find one. You can contact the Cook County Clerk's office to see if they have a copy of her death certificate (I think you can order copies for $17) at http://www.cookcountyclerk.com/vitalrecords/deathcertificates/Pages/default.aspx
I looked on the family headstone and at all of the surrounding headstones to see if Fred's name was there, but unfortunately it wasn't. Unmarked graves are a pretty common occurrence. For whatever reason, a headstone may have never been placed, or it may have been placed but then toppled or went missing. Your best bet at this point may be to contact the cemetery office to see if they have any additional information. Their phone number is 773-631-0900. Their office hours are by appointment only, so it might be a bit tricky to get a hold of them.
I did find Fred Stevers' obituary in the Chicago Tribune archives. Hope this is helpful.
Obituary published in the Chicago Daily Tribune, June 9, 1922:
"F.D. Stevers, Trade Board Member Since 1887, Dies
Fred D. Stevers, a member of the Chicago Board of Trade since 1887, died Wednesday at his residence, 6804 Hurlbut Street, Norwood Park. All his life was spent around the board of trade, his father, the late M.D. Stevers, having been one of the pioneers of the grain trade and of Norwood Park. Funeral services were held yesterday, burial being in Union Ridge Cemetery. His widow and sons, Martin D., Harold D., Lynden A., and Fred D. Jr., survive."
Fred Stevers You're very welcome, I'm happy to help. I searched for Fred's headstone among the other Stevers in that lot, but unfortunately I couldn't find anything with his name; it's possible that he might be buried somewhere else in the cemetery. The Chicago Genealogical Society has a book for sale that lists all the known burials in Union Ridge and where they're located in the cemetery; if you could find out what section he's in that would help greatly. I will look for his headstone again the next time I go.
George and Martha Ellis I see they are your gr gr grandparents as they are mine also! I have a copy of a handwritten bio regarding George's "Life and Work" and am interested in putting some of the info on his memorial. I see that you asked to manage their memorial. It is so coincidental that I find you now as I only just started on Find a Grave. I descend from their daughter Amanda Ellis, then her daughter Martha Adams Mitchell 95226678 (my grandmother.) I would love to know how you and I are related (third cousins?) Thank you!
RE: Stivers/Stevers Laura - I'll see what I can do to help. I haven't come across Benjamin yet but I'll keep looking. How are you related to Isaac? My interest in the Stevers family comes about because we live in the house in Middletown that was owned by Allen and Laura Morgan Stevers. It was built by Laura's family. I have tried to connect Allen's father Isaac to the Isaac buried in Bethany Cemetery in Truthville but with no luck so far. Can you confirm that connection? I just created a Stevers Family Virtual Cemetery on my contributor page and added all the Stevers that I am aware of. Let me know if you have found any others.
