It was handed down in several branches of the Widney family in America that a Widney ancestor living in Ireland in the late 17th century had come there with William of Orange and fought for him at the 1690 Battle of the Boyne. It was also handed down that he was therefore granted an estate in County Tyrone. I've found no evidence of Widneys of any conceivable spelling in County Tyrone, but I have found three deeds placing them just outside Tyrone in Killymurry, County Monaghan. The first deed was dated 1724 and conveyed one-half of Killymurry from father to son in anticipation of an upcoming marriage. So, the father evidently held the property for some time prior to 1724.
While the Boyne story cannot be confirmed, one Oliver Udny was a Captain in the Scots Brigade in service of the United Netherlands from 1607 to 1610. In 1621, then, Oliver Udney was leased a property in Cran, County Cavan, Ireland, roughly 33 miles south of Killymurry.
Notably, native Scottish vocalist Jock Duncan recorded the song "Bonnie Udny" with the words "Oh Widny, bonnie Widny, at present adieu ..." When asked about the name, he said, "Never naebody heard o Udny: 'It's Widney boy - are ye gaun doun tae Widney the nicht?'" http://www.springthyme.co.uk/1039/cd39_08.htm
So, to my question ... Is there any Dutch surname that could possibly be a match for Widney? I searched Netherlands records extracted at familysearch.org and wasn't able to find even one occurrence of Widney, of any spelling that I could think of. However, they are record extracts only and not originals.
Also of note ...
1. Oliver Udny appears still in County Cavan on the 1630 muster roll, with the spelling Owdny, along with a Nicholas Owdny.
2. A Nicholas Widney, possibly a son or grandson of the above Nicholas, died in Killymurry in 1731.
3. Another member of the Killymurry family was a Presbyterian, being an elder in the Monaghan Presbytery in 1713.
There are two profiles to which this relates: Udny-6 and Widney-32.
