You should submit your DNA to familytreedna for the AGNEW surname. Your Egnew surname most likely was spelled Agnew but somewhere along the way the surname was misspelled.
I'm hoping to convince a male descendant of James Agnewwho we can prove descends from James Agnew m. Rebecca Scott to submit his DNA, so if you submit your DNA and this male descendant submits his DNA, you would know if you do or do NOT descend from James Agnew m. Rebecca Scott.
James Agnew b. 1711 in Ireland died Oct 1770 Adams Co., Pa. His descendants moved to other counties in Pennsylvania and some by the 1800's to other states in the U.S.
I know of two other Agnew lines who lived in Pennsylvania in the 1700's. Maybe your Egnew's were related to these Agnew's. ... JOHN AGNEW b. ca 1774 (place of birth unknown) d. 1831 in Venago Co., Pa. We do not know his parentage. John Agnew married Rebecca Smith. ... DANIEL AGNEW b. ca 1775-1778 in Belfast, Ireland d. 10 April 1835 in Sinking Valley, Tryone Twp., Huntingdon Co., Pa. Daniel Agnew married Catherine Neighbour.
My 1st cousin Richard Agnew, descendant of Levi AGNEW and First Name Unknown AGNEW, recently submitted his DNA and so did David Agnew a descendant of Daniel AGNEW and Catherine Neighbour.
