If you're a parent, chances are, you're siblings have the same same elements with your sun signs or rising , or sometimes compatible with their grandparents (if they are living together). But closely, to their own parents. Have you noticed? If non of siblings have no compatible sun ,then check their rising. I usualy observing that, and I believe it's the Universe who made it.. So look at every family, they stick together bc they undrstnd one another.. Still theres no perfct family. My point is atleast.. So by the way my dad a pisces gem rising, Sis a scorp cap rising, me cancer scorp riser, bro1 cap aries riser, bro2 leo scorp rising, and mom a gemini virgo rising.. Moms favorite is my cap brother. Just like that. Aside from that, ure other relative play a role 2, like u'l have 1or2 cousin with same age range who are also comptble with ur sun sign..and that cousin wud be ur buddy-buddy. Anyway, just my observation
