Coffey and Mcmurray Families IN the Cranfield OR Kilkeel Area

Hi. Iam looking for Info on the Coffey and MCmurrays who lived in that area years ago My gig grandfather was Robert Coffey he married a Susanna McMurray Their kids were born at Cranfield Susanna is buried there At sometime Robert Coffey moved the family to Warrenpoint He remarried a woman named Meg MCKibbon They had a son named Dave Coffey. He had about 7 kids by Susanna. One being Mary ( my Greatgrandmother) ) she married a Robert McGuffin in Warrenpoint They came to Canada in 1913 Most of the Coffey kids left Ireland I am wondering if Robert Coffey had any brothers or sisters And if there are any McMurrays in the area I think Susanna McMurray had siblings ( will have to get my papers out) only recently have I found anything about the ancestors . I live in Ontario. I am also related to the MCGuffins from Warrenpoint. Hope to hear something thanks!
