My Bovenizer connection is remote - my grandmother's first cousin married a man whose greatgrandmother was a Bovenizer.
Despite a long connection with Trinity College Dublin, I never made the acquaintance of Harry Bovenizer, who worked there as a librarian for many years. However, I have just been reading some amusing tales of Harry and his family in Michael de Barrabeiti's chapter in Trinity Tales: Trinity College Dublin in the Sixties (Dublin: Lilliput Press, 2009). Harry's father, known as Barney Bovenizer, was the gate man at Mount Jerome Cemetery in Dublin.
A quick trawl through the Irish Civil Registration Indexes suggests that Barney was a nickname for the above Henry (7 in 1911) of Rathmines Avenue and that he married Flora Isabella Stedmon/Stedman (1932, Q3, Dublin South, v.2, p.363).
Their son Henry J. Bovenizer (b.1937, Q1, Dublin South, v.2, p.401) must be the Trinity College librarian.
The older Henry (45 in 1911) was surely the Henry Shier Bovenizer whose christening is listed at
