Technically, yes. Google could track what ip address is sending what requests from your household. They would only be able to track your household not your specific computer due to the NAT on your router. In reality, ISPs change your ip address a number of times over a year, so Google couldn't know when the change occurs without some extra knowledge (such as you being logged into your Google account, but that also isn't fool proof because you could log in any number of places). Google probably doesn't care that much about an individual's data and would not invest the time and resources to build software to track information on the level you are talking about
