Edith Kear 1823-1906 and William John Kear 1820-1888 (General)
I don't think this is the same family. The mother's name listed is Esther. Through all of the research I have done on this family, I am not aware of a second sibling to Caleb. And having one sibling so much younger would be rare unless Edith remarried, which she did not.
I am looking more for the information about William John Kear as I have hit a wall with any parents for him.
