Greetings, with the current Hidden Service protocol, your onion address is leaked to a small number of Tor relays -- specifically, your onion address is leaked to the HSDirs that host and serve the descriptor of your Hidden Service (That's 6 HSDirs per time period and they rotate every some hours.). If your threat model includes those HSDirs being malicious (which should probably be the case), then I would advise you to not do stuff like homeaddressxxxxx.onion. For what it's worth, there has recently been some discussion on plugging that leak.
