Hi MargP, interesting that you should ask that - I don't know - but have been trying to answer that very question this morning! I only know that he is described as a Civil Engineer almost exclusively on any record I have for him (sometimes just civil engineer as on the marriage records, 1911 Taff Vale Railway and 1939 "Roads and Railways" in Cardiff). Locating an Evan EVANS in military records is definitely proving to be time consuming but, serving in WW1, for example, would help me narrow down where he may have been 1914-1918, which would help me with other lines of enquiry that I have. Would a military connection have made a difference to the two marriages? I also googled this issue and someone had commented that they didn't want the one side of the family to know that they had already been married so wanted to "stage" a second marriage - perhaps this happened here....
