I often tell the story of how surprising simple some of our searches are. Well this one is the complete opposite. It was so confusing I kept each webpage I had to accessed open so that I could continually cross check the next piece of information with the last. I currently have 26 tabs open and I estimate that it took me 30+ hours of research to get to a result.
The first part of the search was completely straight forward. It started with a message from Cath N, a friend of mine who is connected with the Yass RSL. During a recent house clean up, two WWII medals were found and handed to the sub-branch. It didn't take me long to work out the recipient was 55125 Vincent William Bingham who served in the RAAF. Vincent was married to Pearl and in 1941 they had a son, Grant. However, Vincent died in 1947 and Grant in 1961. All this information came from a website which documents headstones.
By using a search combination for the names Pearl Matilda and Reuben on Ancestry.com I found that Pearl was married to Reuben Crymble but there was a large gap between when Pearl was in the electoral rolls using the surname Bingham and then Crymble, that is because her second marriage had been to Alexander Bradley. Reuben was husband number three. There were no children from either marriage so I stated all over again.
