Hello BOTH Do not know much about DOWLAIS area . You should be able to get LICENCE records from GLAMORGAN ARCHIVES in CARDIFF . These might tell you how long your families ran or owned pubs weather the names of pubs changed etc . There are also somtimes reports in local newspaper about licence renewals or applications for licence.
