Called twice. First time, didn't leave a message, second time (within 10 minutes of the first call) I answered. Asked for me by name and said he was from a law firm and gave me some old phone number and said it was regarding a case from 10 years ago regarding a man named Clayton who was either my father or uncle. There is no one named Clayton in my family and we have never been to Texas. He mentioned my estranged mother's name, though incorrectly. Possibly phishing for information, but I gave him none. Though I am a little bothered at how he got my unlisted cell phone number
