Yes - I'm fairly sure (95%) it's 1910. From 1939 Role info he says his OB is 31.01.1910 which makes him most likely a James Bolton W.Derby 8b 320 Jun 10 record. However, can't rule out in the same section James Bolton Liverpool 8b 98 and a little later James Edward Bolton W Derby 8b 331 Jun 1910 (although he's an outsider as Edward seems not in keeping with other family names..)
His Mother was Alice Brown. James Bolton was illegitimate. I'm guessing 'Bolton' was the Father's name but at the mo, it's only a guess!
