Thanks for this post. My name is Alastair Haines, son of Marion nee Calpin of York, daughter of Harold Calpin, twin of Richard, the only sons of this family to survive the war, since they were too young to enlist. Harold had four daughters, my mother being the youngest, Richard had two.
Richard's daughters still live in York. My mother's two surviving sisters live in London and Melborne. My mother, sister and I live in Sydney.
Richard's daughters and wider family would be the best point of contact for more extensive and reliable information addressing your questions.
