Might be a debt collector - asked for the person who had my number six years ago. She and her husband were financial deadbeats and Republicans (got a lot of calls from them, too).
Answered the call. The lady gave a name and said she was calling on behalf of Habitat for Humanity. I told her that we give when we can and to please take us off the call list. I don't know how she knew our name in connection with our land line - we are not listed.
