William Farquhar and Catherine Hawkins from Aber ?????

I am the son of Ronald Lloyd Hill, grandson of Roy Clifton Hill(brn 2/23/1888--died 10/12/1965) Married to Ruby Mae Dennis. Great grandson of William Arthur Farquhar (or Hill) (brn 7/19/1860 Franklin,NY--died 1/21/1934 Middlesex, Ma. ) marriedFlorence Estelle Smith and later Elizabeth Fields. Great great grandson of William Francis Farquhar ( brn 1837 Franklin Centre--died 1907 Steuben, NY ) Married Marry Easton 1860. His parents were William Farquhar (from Aber--Aberdeen Scotland?)brn abt 1804and Catherine Hawkins brn abt 1808 ( where ? ). I am looking for any information on my family, which I assume goes back to Aberdeen Scotland and also why the name change by William Arthur. Any help would be greatly appreciated.
