*[[Helen and Judith of Szony]] (Hungary, 1701 — 1723), [[pygopagus]].
*[[Chang and Eng Bunker]] (1811–1874). The Bunker twins were born of Chinese origin in [[Rattanakosin Kingdom|Siam]] (now Thailand), and the expression ''Siamese twins'' is derived from their case. They were joined by the areas around their [[xiphoid process|xiphoid cartilage]]s, but over time, the connective tissue stretched.
*In 1834, a set of conjoined triplets were born in [[Catania]]. Two of the heads shared a neck while the other head had its own. The infant, a male, was described by Galvagni.<ref>{{Cite web |title=Digital Collections - National Library of Medicine |url=https://collections.nlm.nih.gov/bookviewer?PID=nlm:nlmuid-57221200R-bk#page/278/mode/2up/search/supernumerary+limbs |access-date=2022-09-22 |website=collections.nlm.nih.gov}}</ref>
