In the 1922 and 1925 Directories, 55 Lloyd Street is named as The Rowans and occupied by Mrs R W Jones as apartments.
Around 1926, a Mr R W Jones appears at The Rowans in St Andrew's Place. This begs the question as to whether the Jones family moved virtually across the road and took the house name with them. Presumably the Parry family at some point before 1933 take over 55 and re-name it as Almira. A puzzle is that the 1929 Directory shows a W Neal at 55 The Rowans as apartments!
Trevor C. Parry was the eldest son of Griffith and Clara Parry, Almira, who died in 1946. He served in the RAF in WW2.
As an aside, Mr R W Jones (1887-1983) was clerk at Chamberlain, Johnson & Parke in Trinity Square (1900 - 1979. He was still working into his 90s and the last Llandudno man to wear a wing collar, which he did each day on his walk to work. Conwy Archives have a photo of him complete with wing collar - just put "The Rowans" in their search box.
