Harry Vance, s/o John, born in West Virginia, USA, 1886, was sent to Derry to live with an uncle after his father's death in 1897. This uncle could be VANCE or GRAHAM (mother Maria Graham). Harry returned to US 1903, age 16, a month before his 17th birthday.
Finding Harry in the 1901 census is the only hope I have of finding the place of his ancestors
I will be grateful for any information of advice.
