Appreciate some advice regarding 2nd account, attached to my main email address- *******@gmail.com. 

My registered account email-********@gmail.com has been active on family subscription for some time. 

*********@gmail.com is rarely used these days so decided to change details, its a concern to be informed of an active account already linked. 

********@gmail.com does seem to be active, Unsure how it's happened but would prefer correct details on active subscription. Don't know how or what to do.
