Clay Squire

Im searching to see if Clay Squire and Henry Clay Squire is the Same Person . My Clay Squire was born in 1840 in Ohio and was killed while hoeing his garden i found him in the 1880 Census for Pierce , Texas Co,. Missouri. he was married to Elizabeth Dutton and she remarried after he was killed to a David Henry Fry in 1883. so he was killed between 1880 and June 1883. found a Henry Clay Squires buried in Oakside Cemetery in Shannon Co, Missouri and the headstone said born in 1845 and died in 1881 ,. He is buried next to his father Henry Squires . So i am searching to see if these are the same clay Squires. wish me luck haha.
