Hi. My grandfather, Edward Earl Johnson, had a son from his first marriage, before he married my grandmother. His 1st wife's name was Rosa, but that's all I know about her. I have the following info about my grandfather:
1926 20 Jun Birth
Portsmouth, Rockingham, New Hampshire, USA
World War 1 draft registration: 1945 Age: 19
Hopkinsville, Christian, Kentucky, USA
Marriage to Mary Anna Boston
Portsmouth, Rockingham, New Hampshire
This was his marriage to my grandmother, so his marriage to Rosa was before 1951, as well as the birth of their son.
Kittery, York, Maine, United States of America
He was a good grandpa.
