He married Isabella in 1912. Has three children between 1913 and 1916. Disappears for a bit (Isabella on 1921 census as head of house and married). then further child in 1926, after which he is never heard of again. (But this suggested to me perhaps a period of working abroad for several years, maybe starting another family. Returning 1925 ish, it not working out, and him returning abroad again.)
