My great-great grandfather, William Thompson Cordner appears on the 1881 census in Boston (USA) "born 1841, Ireland". He named one of his children Marie Massereene Cordner and an old family tale (yes, one of those!) says that Cordners worked on Viscount Massereene's estate in the 1800s.
Given that this is all the information I have (IGI, Rootsweb and GenesReunited have no useful info that I can find and I've tried googling with no luck), can anyone suggest any website links I could try?
Any help would be greatly appreciated ('cos it's desperately needed - I'm stumped!)
Many thanks
Philip
