This family bible concerns the immediate family of Royal Cooper Vilas. The earliest hand written date in this bible is December 12, 1878. The family names are Royal Cooper Vilas and Carrie Augusta Ward - Dec. 12th 1878 at Newburgh, NY. Their children listed as:
Royal Cooper Vilas Jr. born August 21st 1879 died 1932
Elsie Vilas born October 17th 1880
Ward Ashman Vilas born January 22nd 1882
Eleanor Vilas born January 14th 1884
There is also some indication that Royal Vilas had been previously married, in 1864 to Mary Emma Cornell (born 1845, died 1873) but I don't see any children from this first marriage.
Reviewing some information from the Internet, it appears that Royal Cooper Vilas is the son of Royal Vilas (3 April 1804 at Alstead, Cheshire, New Hampshire - died 1874) and Mary Ashmun (1808-1886).
The children of Royal Vilas & Mary Ashrum are given as:
