I recently found an autosomal DNA match with "66northstar" who writes me "My Great Great Grandfather emigrated from County Londonderry to Canada in 1833. His name was Robert King and he came from Dungiven. He was born 1813 in County Londonderry and died 3 Jan 1880, North Augusta, Ontario, Canada. His father is also believed to be Robert King, born 1788 in County Londonderry. His wife was Margaret Wellington and born 21 Jun 1812, County Londonderry (probably Londonderry City). She died 31 Oct 1845, North Augusta, Ontario, Canada."
I, too, notice there was a Robert King living at Moyes -- there's no Robert at Dungiven shown in the 1831 census as far as I can see. Kicker for me is that Moyes is the townland where my 4x great grandfather John Cochran(e) (ca. 1760/70-after 1831) and his brother Samuel Cochran(e) lived around 1805-1814 when their children were baptized at Ballykelly. It could be Robert King, Sr. was married to a Cochran, or one of the allied lines I'm connected to.
And it just might be this Robert King is related to Frederick King in some fashion.
