Thankyou for your reply. I have bad news and good news for you. The bad is that I was messed up with my 'Edward' Joughin. I was actually looking for Edward D Joughin, not Edward C Joughin, but didn't realize it at the time I posted this message.
However, in the midst of all that, I met via email a man named Philip Allen who is also a Joughin descendant and is an expert on the four Joughin families from the Isle of Man. He has a book in the works, in fact, but says he may not get it finished until he retires!
He is very likely to be able to help you solve your Joughin mysteries.
Please email me at my home address and I'll give you his email address in England. Tell him that I referred you to him.
Sincerely, Carol Mohr Langley, British Columbia, Canada
