My grandfather's name was Charles Francis Holton Tewkesbury. He lived in Detroit, Michigan with his wife, Ethel Martha Bradshaw. I think Ethel was Canadian. Charles was an electrical contractor most of his life. I think his company was Traverse Electric. They had 10-11 children: Charles Tewkesbury living in FL, Frances De Nio from MI now living in GA. The other children have all died: Charlotte Richards (MI), Phyliss Goldsborough then remarried to become Phyliss King (Algonac, MI), Jean Radakovic ( Ann Arbor, MI), Helen Davis (Detroit,MI), Eleanor Wagner(Detroit& Marine City,MI), Arthur Tewkesbury (Marietta, Ohio), Geraldine ?(Ann Arbor, MI), Raymond Tewkesbury (Detroit,MI died in infancy), William Tewkesbury (Hazel Park, MI).
Anyone with other info related to Charles would be helpful.
