I'm from the Yourell family, and was wondering if there's any known connection between the two names- it seems like an easy variation to make. I've found a huge amount of Yourells in the 1901/1911 Irish census and it seems that there are Orrell roots there as well. The furthest back I can trace my personal roots are to an Edward Yourell Sr. who came from Dublin to Canada at age 12 as a stowaway, then later moved down to America- if that helps. I believe his brother made his way to Australia.
If there's any connection I'd love to hear about it, thanks.
