Many Thanks Jeff. I'm not familiar with Swansea, and thought that Tyrpenry/Tirpenry was the name of a district rather than a road.
I gather that there was also a Sunday School in what is now Nixon Terrace as well?
I also thought that my Grandmother Margaret Rees's family were Methodists rather than Baptists... Certainly her father, Evan Rees was Baptised in the Weslyan Methodist Tabernacle Chapel in Morriston in 1836. I have his Baptismal Entry.
