As I said, in the strictest sense I did use Google and AllHomes as supplemental sources; however, and this is key, not a single edit would be any different had I not touched Google Maps or AllHomes ~at all~. I simply added them as a courtesy, and because I am a new editor I was unaware of Google and the Domain Group's copyright policies. I apologise for any misunderstanding from my wording in the changeset note.
Thanks and apologies again.
