yeah, I get that. Taking estrogen will change the way you look - one neighbor of mine told me he thought I looked 20 years younger, this was after taking estrogen for 6 - 8 months, lol. So cis people may be more clueless than you think, but at some point it will be an issue - and it definitely would be best to trust your family and be able to transition openly with them.

Though I just realized - family could mean you are married and have kids, or it could mean you're young and haven't left home yet - and those are two different situations, much easier to leave your family if you're not the parent 😅
