Oh Wow !!!! Thanks for much for responding Ricky and confirming some of my suspicions at least. I have Gladys as born in Conwy on 31st August 1897 then moving to Warmington with her brother and their dad after 1919. Gladys met Rowland Pullen in Warmington and they married in Oundle in April 1920, and Glenys arrived 4th March 1921. Walter James arrived 13th April 1922, and I presume they moved down to Sussex shortly afterwards, because the sibling Peter was born there as you say.
Apologies if the Salloum marriage came as a shock but I am interested to know whether Edward Salloum was linked to the other wedding in Hove involving Hilda who married another Salloum. They surely must have been related with such a rare name for Sussex at least.
I would like to recount the rest of the Welsh story here which includes a huge slice of irony. My father was a very keen railway enthusiast and was often hanging around railways when he could, particularly of the LMS railway. He told me once how he and his brother went to Deganwy very near Conwy to stay at Auntie Gertie's BNB. While he was there there was a terrible rail disaster when the up Irish Mail from Holyhead to Euston collided with a locomotive at Penmaenmawr - a location just across the estuary from where he was staying, and he said he heard the terrible noise from the collision. Several hours late he remembered the wrecked locomotives being hauled onto Llandudno Junction loco shed to clear the line.
Well it turns out that a chap name Charles Whitmill had started work as a teenager i nthe loco sheds at Willesden, then gradually moved up the ranks via Watford Jn and Crewe to become locomotive superintendent at Llandudno Jn where he retired. Charles wife died and he befriended a lady named Gertude - remember that name !!!
Walter Rimes, after seeing both of his children Robert and Gladys settled in Warmington moved to Birmingham and met a lady name Gertrude from Smethwick. they married and lived in Edgebaston for a while before moving to Conwy where Walter had lived previously. Walter died in a nursing home there leaving Gertrude a widow. After Charles' wife died he and Gertrude became friendly and married, but he wasn't long for this world and he eventually passed away in the same nursing home
that Walter saw his days out in.
Twice widowed Gertrude kept the B&B at Deganwy and thus my father and his family stayed there those years later. What was disappointing for me given his love of railways was that he unknowingly stayed with Aunty Gertie who was married to the locomotive superintendent of the shed there. I am sure he would have been totally in awe had he known.
One of those fascinating twists of family history we all love.
Thanks again Ricky for helping with the story. Much appreciated.
