Royal Irish Constabulary
My g-g-grandfather James Robinson was discharged from the Royal Irish Constabulary in 1870. The births of his children had been registered in Atherny and Monivea, so I expect he settled in the area after retirement.
The earliest reference that I have to him being a postmaster is on the 1884 marriage certificate of his eldest son Alexander, although it doesn’t mention that the post was at Woodlawn. The first mention of being a postmaster at Woodlawn was in 1888, on the marriage certificate of my g-grandmother Ellen Anne Robinson. I assume he held that post until his death in 1899, after which his daughter Susan took over.
