West Virginia Law

Can anyone answer what the legal aspect is for mineral rights being transfered to step children when a mineral owner heir remarries in West Virginia? The scenario in our family is this: (1) Mrs. Smith is an heir and is a widow, but has children from her first marriage. (2) Mrs. Smith remarries to Mr. Jones and then she pasees away and Mr. Jones receives her property. (3) Mr. Jones also has children from a first marriage and then Mr. Jones passes away. (4) Where do the mineral rights end up going to? Do they go to the original heirs children or to her stepchildren? Please help!! Thanks very much
