I wouldn't suggest looking at the edit history at all, just the most recent revision as of whatever moment in time is chosen. If vandalism is found, then and only then would one look through the edit history to find out when it was added.
That only works if the article is very well referenced and you have all the references and are willing to fact-check everything. Otherwise you will miss subtle vandalism like changing the date of birth by a year.
