Thanks Colette,
Sorry delay in reply, illness prevailing here and 1901 Cesus correct, Have visited this abode 2008 which was held by my Family till about 1975. looks like Michael died C1902.
NB: My error as Michael(My GG/Father) married Caterina Myles 1824-1810. His Father was in fact William GAVANAGH 1780-? he in fact married Elizabeth 1782-? at which point we stall!
my grandfather John was a renowned Stonemason in SKERRIES and I believe there is a ploliferation of KAVANAGHS of there not connected so your Line might not match? The name underwent several changes from GAFFNEY, GAVANAGH KAVANAGH etc. over the years. Mike
