The Google Account is under an alias.
While that's a probability, I really think for all practical purposes, it's an impossibility. I've had this Google number for a long time-probably over 5 years. And while I'm in Texas now (and so is the lawyer), the Google number is from another state. To think a lawyer with my name had the same out of state phone number over 5 years ago really has to be an impossibility for all practical purposes.
No I'm sure that somehow from the text he was able to look-up my first and last name. He then googled that and found a 'wrong' me.
I don't think I did anything to compromise my identity. I don't have another phone to test it on currently. But I did text my regular number from the Google voice number, and on my phone it comes up as Google Voice.
I'm going to assume (if we posit that I didn't somehow do something to reveal myself) that whatever he did isn't very common at this point as I don't think it's ever happened before -or at least no one before has ever called me on giving them my fake name (well really it's not a fake name-i give them my middle name).
