The Avengers family tree is bonkers
Hank Pym is Ultron’s dad, who is Vision’s dad, who is Viv’s dad
Vision is brain-brothers with Wonder Man, who is actual brothers with Grim Reaper
Vision had kids with Scarlet Witch, who is siblings with Quicksilver as they are Magneto’s kids
Magneto has another kid, Polaris
Vision & Wanda’s kids are Wiccan and Speed, and Wiccan is married to Hulking, who is the child of Mar-Vell
Mar-Vell had two other kids, Genis & Phyla
Quicksilver had a kid (Luna) with Crystal, who’s part of the Inhuman royal family
Ultron made wives for himself TWICE and had another kid in Victor Mancha
Hank Pym sorta kinda had a kid with Tigra (William), and had a daughter from his (dead) first wife (Nadia), who was adopted by his second (and ex) wife Janet van Dyne
Also Ultron’s first wife is based on Jan, his dad’s wife. This is arguably not part of the family tree but I wanted to mention it
