Well, my 2 cents...
I know I'm alil late in sharing my family's similarities and such, but, Imma do it anyway.
Unfortunately, no-one in my family has their birthtimes except for myself, and possibly my lil cousin but I dont know when he was born so he doesnt count. So no Ascendants.
My mom, aunt, and I were all born Libras. My aunt & I both have Mercury in Scorpio. Thats why we tend to have a passion when we speak.
No Venus commons really.
3/4 guys in my family (I dont have my uncle's birth-year) have Water Moons (2 in scorp [grandpa and daddy] 1 in cancer who is my lil cousin).
3/4 woman in my family have Firey Moons. Gma & I have Aries, Mom has Leo, and my aunt has Cap which is a cardinal sign. Thats why us woman seem to be so much more aggressive emotionally than the guys. 3/4 of us also have Cardinal moons. 2 od us are double fire-cardinal (aries).
Mars....no repeats.
Jupiters...Gma & I both have Aries.
Saturns...My cousin and Mom both have Aquarious Saturns.
And both My Gma and Aunt have Saturn in Cap. My Gma & Julie can be pretty hardcore when it comes to obeying rules...whereas my Mom is alot more flexible. Dont know much about Nick yet. Interesting how my Aunt was born like my Grandma and my Mom went a totally different way.
Uranus's...My Dady & Aunt both have Uranus in Leo...but that's only becuz they were born about 4 monthes apart and we're getting into the Generational items now so....they'll have all the same things now probably. No other repeats.
As for Sun signs, the woman are all Cardinal signs (3 libras and a cancer) plus my Dad (cancer) and the other men are mutables and fixed. A Leo, A Sag, and A Virgo.
Hope yall find this somewhat interesting even tho my family doesnt seem to pass on much astrologically.
