I dont know if it is the same person, but through my research i found a Grover C. Widener, born January 18, 1892. His parents are William D. and Eliza J. S. Widener.
It states that Grover married Bertie Heath, daughter of Thomas and Mollie Heath.
This research was found through the Washington Co., Va birth records.
If you feel this is the person you are seeking, please let me know, i have the rest of the ancestor links to Grover, but i havent found any children under him...so if you have any helpful information please contact me...
