In the Matter of the Estate of Seader 2003, Wy 119, 76 P.3d 1236 (2003). Please answer the issues that were before the court:

a. Whether the doctrines of equitable adoption, adoption by estoppel, and virtual adoption are available under Wyoming law to allow the descendents of a predeceased stepchild to be considered lineal descendants of their step-grandfather under the anti-lapse statute.

b. Whether the district court erred in concluding that the testator's will not evidence an intention that the share of a predeceased devisee pass to that devisee's children?
