Thanks Rathmore. In previous Rootschat searches I was guided to that site but unfortunately have been hitting brick walls since, especially on the 3 Williams. I enclose a pic of the marriage certificate which has a Squiggle before Dominick Street, is it Upper or Lower. John Cathcart was a House Servant aged 20 in 1848 so was he resident in his Lord & Master's house? Why is Anne Bowles listed as also resident there? Was it her father's house?
Later he was in Preston, Kendal, Alloa and Lancaster and always a Servant of some kind + horseman, coachman, ostler. Did he follow his Master to these locations?
I have suspicions of connections to the Army, Brewing & Distilling and the Wesleyan Methodists.
Sabbeth seems to be a contraction of Elizabeth and not the biblical Sabbath. Although there were Needhams in Ireland there were also Needhams from Bolton-le-Sands in Lancashire, the place where Jane Dickinson came from, John's 2nd wife after the demise of Ann Bowles.
On the certificate William Cathcart is a Slater, yet subsequent mentions have him as a Gardener or Farmer. The 1858 marriage of Catherine Maria Bowles to Robert Wilson, a Butler, and son of John Wilson, a farmer, and William Bowles is no longer a Steward but a Mercantile Clerk. (if he is the same William as Anne's father, as seems likely).
Are there property owner occupier records for Dublin covering this period, ie Dominick Street and Merrion Street?
