In my tree I may have a Sarah HAVERON m. Robert BARKLIE of Larne & Inver. (Both born around 1790-ish). I'm curious if the Patrick Haveron in Sheriff's Land in 1900 (and your Josephine who shows up in his household in 1910) might be related. It's a curiosity as I had kin living at #6 Sheriff's Land 33 years before your Patrick resided there in 1901. We know from a Griffith's Valuation entry that Eliza McBride Curran was a resident there until about 1868. Her son Samuel Curran, was married to a Sarah Brickley. A researcher with whom I worked last year has hypothesized that Sarah was actually a Barklie and not a Brickley and that she may have been one of the children of Robert Barklie and Sarah Haveron, born 12 Nov 1823. The baptisms of several other children of Robert and Sarah were also registered in the Inver Church of Ireland records. (I hope this is not too convoluted...I'm happy to clarify).
I look forward to sharing info with you.

Monica
