Have you tried searching for "Glenny" last name without any first name?There is plenty of information at FamilySearch.com and Rootsweb.com, especially if your family came from Northern Ireland or Scotland.

There is information on the web, but I can't get you any without some background.You see, there's Northern Ireland web sites and also Scots. Let me know where you can the family back to and I can give you some leads.Good luck!
