I came across your posting while researching my own Haggarty/Haggertys. However mine were in Newport, Monmouthshire, Wales I suspect they were from Ireland before that.
Anyways, quick google search on "Seven Steeples" brought up this photo of the Seven Steeples Graveyardhttp://www.flickr.com/photos/afuturecastle/1065688795/
