Hi Tracey
I searched a variety of sites for Blanchfields in Waterford with very little luck I'm afraid.
There were none in the Tithe Applotments 1823-37 or the early Irish Censuses
The only 1 was this one from Griffiths Valuation (free site):

The only 1 for Edward on www.rootsireland.ie/ was this one which is way too late:

IF this Edward is a descendant of your Edward and IF they hadn't moved since the earlier Edward's time, there could be some relevant Blanchfield records in the National Library R C registers which are free. The records available for Carrick-on-Suir are:
