As mention, William Richard Leeson remarried in the latter stages of 1923 to Clara Matilda Rawbone following the death earlier that year of his first wife. Shortly after marriage Leeson made a new Will listing his new wife as sole benefactor. This move seems to confirm that by this point in time he no longer had anything to do with is two sons, Reginald and Archie Leeson. I have been able to obtain a copy of Leeson's will, page 1 is listed below.
