Okay, I did some testing. It appears that my solution only accounts for current members. So, if the first member has since been removed, using api.php in the manner I suggested will not work correctly. However, if you want use it, below is a revised version of the queries that eliminate unnecessary things. You need to do them in order as the second one requires information from the first. cmtitle=Category:CategoryName&action=query&list=categorymembers&cmsort=timestamp&cmlimit=1&cmprop=ids|timestamp Replace "CategoryName" with the name of the category. pageids=PageID&rvstart=Timestamp&action=query&prop=revisions&rvlimit=1&rvprop=user Replace "PageID" with the "pageid" value from the first query. Replace "Timestamp" with the "timestamp" value from the first query. The user's name will be the value of "user" from the second query.

Example using Category:Help |timestamp first query

second query

|timestamp first query

second query

User: Robin Patterson - Edit:

While Fngplg's method would allow for searching removed members, both of our methods are unable to identify deleted pages. So, if the first member was deleted, neither method would catch that.
