I had no idea you could go back further than 1600! No rush on this, but if you are back in the library we'd be intrigued to see who the Rogers family were further back. Dorothy Rogers, who you found died in 1627, would have married into the Rogers family and changed her name but perhaps theirs a record of her husband or a record of her being the mother of George, William and Richard Rogers who would probably have been born in the 1630' 40's and seem to be the fathers of the later children who were being born in the 1660's, which after all was also plague time.
Looks as if the Roger Rogers you found, who married a Joanne is actually George Rogers, the wheelwright who married Joanne Hinkly in 1639 and then had a daughter, Elizabeth in the next year. I say that because Joanne is a fairly unusual name at that time.
John (the stranger) who might have been a Rogers cousin from out of town, married a woman called Jane and as you found out they had a daughter Margaret christened in 1646. Great to find all this out and yes, it is kind of romantic. Since he's not a Loughborough man and more difficult to trace concentrating on the other 3 would be really good.
Very exciting to think you can go back to the time of the first Queen Elizabeth! Thanks again!
Do you have a theory on why there is a James Stevenson listed as a relative for the birth of Elizabeth Rogers in teh 1770's? I looked for him on the IGI and couldn't find any sign of his birth in Loughborugh between 1730-1760. The only James Stevenson I found was in Market Harborough.
