Francis Henry Bishop, described as an engine man with a stated address of Armagh and father named as George Bishop, a labourer, married Annie Weir of Lisburn in St. Patrick's RC Church, Lisburn, on 20 October 1923, the record can be viewed on the GRONI website:
M/1923/E1/1845/26/193 Francis Bishop Weir 20th October 1923 Lisburn
M/1923/E1/1845/26/193 Annie Weir Bishop 20th October 1923 Lisburn
Annie Weir was recorded as a 19 year old actress, the daughter of Patrick Weir, a showman. A transcript of the church version of the marriage record identifies her parents as Patrick and Annie, with an address of Scotland.
An item in the 1955 issue of the Irish Weekly and Ulster Examiner about a daughter [name withheld by me] of Patrick and Elizabeth Bishop of Armagh (but more recently moved to London), mentions her uncle as Vincent Bishop, living at 63 Callan Street, Armagh. The same story also made it to the front page of the Belfast Telegraph of 4 November 1955, where there is also a photo of said daughter. The GRONI website has a registration in Armagh for a marriage that took place on 17 November 1933 between a Patrick Bishop and Elizabeth Copelton, just a maybe.
