Hi Karen, My Shermans are Silas N. Sherman b. 1772, d. 14 Apr 1849, Son of Nathaniel Sherman and Jerusa Thompson.. He married Betsey Curtis, daughter of Andrew Curtis and Patience Nichols, Their children were Erastus, Nathan, Hiram, James W., Sarah Ann, Jane and Louisa..... Silas could possibly have been a brother to your Justus..... I just have nothing more on his family.... Sincerely, Jesse Thayre Barnes
