Hi Babs:I am not sure if this will help but here goes. My Grandmother was Maria sounds like (Mariah). Maria Smyth.Her brothers were David, Robert and a sister Maggie.They lived on Mill Street in Newtownards.I am not sure as of yet of my grandmothers siblings birthdates but my grandmother was born May 1894 and died June 1976. I would imagine that her siblings were not far off in years in birthdates.
My great-great grandparents were James Smyth (soldier) and my great-great grandmother was Elizabeth Jane Smyth (Cargo). My Grandmother Maria married my grandfather Anthony McKay in 1917.All from Newtownards. If I find out anymore like dates/names I will be sure to pass it on to you!
