Have name-changed for this as it will definitely out me to my family!
Have been searching for information about this colourful character in my family tree and am posting this not in any expectation of anyone necessarily being able to help but in the hope that at some point someone else researching the name Roland G W Hudson on a google search might stumble across this post and get in touch. Or someone who is looking for Roland George William Hudson. Or RG William Hudson. Or Walter RG Hudson. Born in 1919. Definitely now deceased, but not sure if all of his wives are.
If he appears in your family tree too, please get in touch!
