I don't know if this will help, but here goes. My Grandfather was William Austin Jenkins from south Wales I believe, he married Margaret Mildred Thomas in Wales. They both were likely born around 1900. They had three children David Trevor and Anne and moved to Aylesbury Buckinghamshire UK. This is as far back as I can trace the Jenkins. Austin I believe was his Mothers maiden name. He was a miner.
I am currently trying to find out if William had Brothers one possibly Ivor Jenkins. Maybe we can figure this out <smile>
