What the lines say
Jon Snow is the biological son of Rhaegar Targaryen and Lyanna Stark — a secret marriage in TV continuity makes him legitimate, and makes Daenerys, Rhaegar’s sister, his aunt. elle.com.au
Joffrey, Myrcella and Tommen are biologically Jaime and Cersei Lannister’s children, though publicly presented as Robert Baratheon’s — the crown’s Baratheon line is Lannister in blood. en.wikipedia.org
Margaery Tyrell married three kings in succession — Renly, Joffrey and Tommen Baratheon — the busiest single knot of inter-house marriage in the data. awoiaf.westeros.org
The Tully sisters stitch three houses together: Catelyn to Eddard Stark and Lysa to Jon Arryn, while Cersei Lannister’s marriage to Robert Baratheon joins the other two crowns. ablogofthrones3110.wordpress.com

TV-continuity relationship edge list for HBO’s Game of Thrones (not House of the Dragon, not book-only lore): 97 edges, 66 characters, nine main houses plus the Stark/Targaryen bridge. Each edge is one sourced claim: parentage, marriage, partnership or betrothal. Distant ancestors, minor bastards and unconfirmed lore are cut for space; nothing here is invented beyond the rows.
