Joyce,

James Saul married Catherine Delahunt(Delamont) in St Mary Pro Cathedral, Dublin on 14th January 1900. His father was also James Saul and the mother's name is transcribed as Jones? Lambert. Catherine's parents are John Delahunt and Anne Boughlan. Address at time of marriage 20 Marlboro Street. Think this is the right couple. To order the research cert from the GRO in Roscommon you need to know the wedding was in the Dublin North District, registered Jan-Mar 1900, volume 2 page 499. Good luck with the research!
