I'd like to talk to you about where your ETHERINGTONs lived. I am tracing a few ETHERINGTON families in UK and when looking in the IGI for possibilities for my John ETHERINGTON (father of Joseph) who died in 1838 in Southwark, I came across one possibility as being the John ETHERINGTON who married Mary BULLEN in 1793 and that reminded me of your post here.
Separate point - as part of my ETHERINGTON search I have been trying to place all the ETHERINGTONs in Australia. If you have anybody who migrated to Australia I might be able to help.
Looking forward to hearing from you Kerry Farmer (in Sydney)
