Pat, I found your post on the same family on another board which gave some additional information.After reading that post, I think the data I previoiusly gave to you is incorrect and the correct information is the one I thought was wrong.
According to 1930 census, Hamilton Co., OH (Cincinnati) District 463, here is what I found regarding George, brother to John with parents of John and Luella (per your information). If I have it correct, it appears your family is the one from Kentucky and England.
George Abbott age 28 b. Ohio Alma Abbott (wife) age 25 b. Kentucky Eugene Abbott (son) age 2 b. Ohio Luella Abbott (mother) age 50 b. Kentucky John Abbott (father) age 60 b. Kentucky Paul Pierce (brother in law) age 34 b. Tennessee Poletitia Pierce (sister) age 24 b. Ohio
Louella's father is listed as being born in England, mother in Ohio
John's father and mother is listed as being born in England.
FYI - There is another George and wife Lula in the Hamilton Co., area at the same time, age 50 and 45.
