Eventually DNA testing will probably sort this problem out. Statistically sample family's with alcohol problems and those without, I would be a very difficult task as most family's tend to be protective of their family reputations and are not keen to describe ancestors as drunks especially if it may reflect on them. There is little agreement as to whether environment, inheritance or both are cause(s) for the disproportionate representation of females in this pathology. Among the symptomatic phenomena are fabrication (the compulsive telling of invented data or narrative, often with the determinance-addict at its center) and one-upping or one-downing (the automatic modification of quality/quantity of others' citations so as to remove their validity). In psychology, determinance is the perceived causality which persons suffering from certain mental illnesses desire over all events, ideas and persons within their range of perception.
