My Fathers cousin was Leonard Adlam-Hill, who was from Neath, Wales. None in the family know the origin of this double barreled name; I suspect a marriage of an Adlam to a Hill. Leonard was born Nov 1868 and married Sally Penney about 1890.
I have contact with a number of Adlam Hills in Neath area Wales.Adlam does not seem to be an original Welsh name; there is a concentration of Adlams in Wiltshire and Gloucester.
Let me know if you would like more information. Cheers
