Any idea of when he was born, parents' names, went to Australia, etc.? Doherty (and variants one of the most common surnames in Londonderry area).
'Londonderry' can refer to the City and vacinity or the County. In this case 'Glenmurrah' likely to be the townland of Glenmanus near the town of Coleraine (in the northeast corner of the county).
