I don't know Liverpool at all, but I have looked at the Genuki site and discovered 2 churches dedicated to St. Andrew. One is C of E founded 1815, the other is in Rodney St and is Presbyterian, founded 1824. St. Andrew is of course the patron saint of Scotland, so that may be why someone said it was Scottish (Scotch is for whisky and mist, my husband - a Scot - is Scottish not Scotch). Also the Scots are generally more presbyterian in their churches, although there are Catholic, Episcopalian and lots more besides, including the "Wee Frees" (the Free Church of Scotland). The certificate should tell you which one of these two churches it was. At a guess, since David Spratt was born in Ireland, it was probably the presbyterian church and he came from the north.
Just read Chris in1066Land's reply, I reckon he knows lots more than I do judging by the quality of the help he provides, but personally I doubt David was catholic, but I'm prepared to be proved wrong.
My 'Oracle' was of no help on this query - and I think my Halo is slipping, it was the other half suggestion that it was RC - mainly because she was brought up in Scotland - but I would go with your interpretation Nell. Chris
Hope that helps.
