Thanks for contact
I have no further info on the Ringkobing connection except to say that I have eliminated two names Thomas Urey 1832 and spouse Alice Dutton 1831.
Can I suggest that you google for 'Surname Ringkoping'
There are some links to brit names, so there may be
be some sort of info/connect that might help you.
Yours is the first contact since I posted in August 2009, so its nice to see that the message boards can be useful.
I will mail you if I make any sort of progress with the Ringkoping mystery.
