I am not at all certain about the young boy being Harry RENWICK 1910-1934. My mother's identification of the male children in the family of Harry RENWICK 1885-1959 and Jessie RENWICK (née Jessie ASHFORTH 1887-1954) conflicts with some of my research.
I will document this further when time allows. I am hoping the contacts I have made with descendants of this line will be able to help resolve this issue.
