G'day MJB, I have 13 William Becktons in my database with births ranging from 1894, in Sydney, Australia, back to Abt 1686, in Hayton Cumberland, England. The earliest Beckton is one Richard Beckton, father of a Richard Beckton, the latter being born Abt 1676 at Hayton, Cumberland, England.
If you tie into this lineage, please let me know and I will be happy to exchange information. Happy Hunting ;-) Arthur Harris. Hampton Park. Victoria. Australia.
