Checking the IGI (
www.familysearch.org) for William Henry Edwards born c1870 (+/- 2 yrs) there's ones in Cork and Dublin. However, there's a William Edwards born 14 June 1871 Londonderry (parents George Edwards & Catherine Harkin)- although this is a submitted not extracted entry.
If you get William and Catherine's marriage certificate it should list his father's name and occupation which might rule out that last possible birth.
IGI lists 4 children for George and Catherine Edwards (married 1869 Co. Derry) - Anne (1869), William (1871), Paul (1873), George (1877).
