You can count me in! I have lots of Irish R.C. in my ever expanding family file.
From Middlesex Co. - London Twp., Adelaide Twp., Caradoc Twp and even stretching into Lambton County.
To name a few: Callaghan, Walsh, Maher, Johnson/Johnston, Dowling/Doolen, Healy, Collins, Feeney, O'Leary, and of course Morkin, Toohey, O'Meara, Donohue & O'Dwyer.
Re: Sweeney, I do have a Patrick Sweeney, Mary Reardon family (John, Hannora & James) Caradoc Twp., Middlesex Co. if that is any help.
