Ann and I live in Dublin.Both originally from Co. Monaghan which borders on Co. Fermanagh....the Irish home of the Friths?
In following up your info on the Friths I came across the birth cert. for your father.He was born 5th Oct, 1904.At that time your grandfather James Wiltshire Frith was living at 7 Palmerstown Park.My brother now lives on Palmerstown Road which adjoins Palmerstown Park.....both plush places to live in 2007 Dublin....small world.
Located the birth cert. for one son of John A. Frith and Euphemia Wilson.James Frith was born 5th may, 1903 in Belfast at which time John A. and Euphemia were living at 10 Grampian Avenue.John A. was listed as being a dairy farmer at that time.
Unable to locate a birth for a Robert Frith in Ireland up to 1906.
Unable to locate a marriage cert. for John A. and Euphemia as yet.
No further info on the Dublin printers as like you our time is spread over many activities.
