Origin of the Name

I was told that the name comes from a manor and village in Yorkshire called Londesborough.  It is southeast of York, about halfway between Hull and York.  The nearest town of any size is Market Weighton.  You can see the aerial views on Google Earth.  There are numerous Lonsboro/ Lowndesbro/ various other spellings of the name in the phone books for that part of England.   An earlier researcher named Raymond Lounsbury traced the ancestors to the family that owned that manor in the 14^th century.  There are some gaps in the documentation, so some of it is conjectural, as you might expect.  Reliable birth and death records were not kept before the 17^th century in England and there were no immigration records at all in New York.  Therefore, it is impossible to be absolutely certain that the Richard Lounsbury that was mentioned in the parish records of Yorkshire in 1643 was the same Richard Lounsbury that married Elizabeth Pennoyer in 1670.
