A Tale of Two Benoni/Benona Graves

Researching my Graves line from Vermont I found Ira Graves in Ellisburgh, Jefferson Co., NY in 1850 enumerated with his wife Polly (Mary) nee Decker.  His children were listed as Lydia, Gilbert (my 2nd great grandfather), Jones, Mariet, Abigal, Benona, Jane, Lynette (Nettie).  Polly's mother, Sarah Decker, is enumerated with them.   Curious about Benona's line I searched for him and  I found a Benona six years older and born in Illinois.  This Benona went to Iowa where he married Almyra Day 30 March 1865 and where he was mustered into the Civil War joining the infantry Regiment 11 Company C Iowa.  He moved his family to Hayes. McPerson County, KS in time for the 1880 census. In 1900 they are in Sumner Twp, Woods Co., OK.  Their two youngest children, Charley and Laura were married in Garfield Co., OK. At this point, I thought perhaps I had the correct line since Gilbert Graves came to Barber County, KS and then on to Dewey County, OK in the Land Run.  However, I then found Benoni age 30 in the 1870 census still in Ellisburgh, NY with his mother, Mary, age 67, and his sister, Nettie, age 25.  This made me even more curious about who was this other Benona/Benoni.  I checked the 1850 census again and found Benona age 16 in Joshua, Fulton Co., IL living with Jesse Graves age 58 born in VT, Lucinda age 52 born in VT and Elias age 13 born in IL. This line went from Vermont>Illinois>Iowa>Kansas> Oklahoma. My line went from Vermont>NewYork>Kansas>Oklahoma. While they took different paths, I wonder if Jesse could be a brother to Ira?  Both have sons name Benona.  A genealogical mystery to solve!
