In 2010, Roy Martin and his wife, Alice; their son Hiram, and Hiram's wife, Myra, acquired title to a 240-acre farm. The deed ran to Roy and Alice Martin, as joint tenants with right of survivorship; AND to Hiram and Myra, as joint tenants with right of survivorship. The deed between Roy and Alice AND Hiram and Myra created a Tenancy in Common. Alice Martin died in 2012, and in 2015 Roy married Agnes. By his Will, Roy Martin left his entire estate to Agnes Martin. When Roy Martin died in 2020, Hiram and Myra assumed complete control of the farm. Were they correct? State the interest in the farm, if any, of Agnes, Hiram and Myra upon the death of Roy Martin in 2020.
