Long time no speak - and apologies for using this forum but your last email address didn't work. Do you have access to GenesReunited I wonder? It's just that I've found a distant link through marriage (involving the British Royal Family) beyween our two branches and I have put in your ERRINGTON line back to the late 1500s in my GenesReunited tree. I've also heard from a Calfornian descendant of John who married Harriet Service (brother of your William who married Jane Mumby).
Let me know if you're interested. My current email address is: firstname.lastname@example.org
