Grand Parents: McGinty & Gallon

Hi my name is John, recently I came across this website when searching for family history. My gran is a McGinty and 1of 5 children who's dad's name is John McGinty from (Gortiness), my (great grandad) who had a brother called Patrick, a sister Mary, who's dad was also called John McGinty (Shane) who were tenant farmer's in Gortiness, my G/grandad was born in Aproximatly 1864. His wifes my G/grandmother called Margaret Gallon or Gallen, was born 15th July 1865 in Cloghan, and married john McGinty on 4th June 1896, at Kilteevoge RC Margaret Gallon's dad was Thomas Gallon a farmer & tailor, and Margaret had a sister called Mary also. As soon as my grand parents were married they left for a new life in Glasgow Maryhill and had 5 children. My grans older brother, Thomas Mcginty married Roseanne Slevin who came from Cloghan also, in Glasgow on 1916. I would realy like to make contact with any of my related McGintys and Gallon family from the present, and if I could get advice on how to obtain copies of my great grandparents birth and marriage certificates. Best wishes, John Cowan Ps, my email is jwcowan@live.co.uk
