The family name is not limited to Basel, and is also found (in variants like Meria, Merian, Meriam and von Merian) in Alsace, Lorraine, Provence, Lower Austria, and Mecklenburg. These families are probably not directly related to the Merians of Basel, but a common root is likely in the former Prince-Bishopric of Basel in the earliest forms of the name Merillate, Merylat, Miregla, Mureglat or Latinized Mariatte. The name probably derives from the office of Meier (meaning steward or estate manager); unlikely, however, is a speculated relationship to the community of Meria in Corsica or to an alleged Merian Abbey in the Archdiocese of Strasbourg, and the same is unlikely with reference to the Marioni nobility from Milan or to de Muriaux in the Bishopric of Basel.

The oldest written reference to the family in the bishopric dates from the year 1385 with the mention of a Jehannin dit Mariatte de Buratte ("'Johann, called Mariatte, citizens, bears witness'"), who resided in a dairy at Bure, Switzerland. This dairy farm had belonged since 1283 to the bishops of Basel, before the dukes of Alsace and the Counts of Mömpelgard/Montbéliard and von Pfirt/Ferrette.

The ancestor of the Merians of Basel is Theobald Merian (c.1415 – c.1505), a Basel episcopal bailiff or steward in Lüttelsdorf (now Courroux) in the Swiss canton of Jura. From him are descended the two Basel branches of the family. The elder line stems from his son Theobald Merian (1465 – 1544), who went in 1480 as a seaman of Lüttelsdorf to Basel and later operated a sawmill on the right bank of the Rhine in Kleinbasel. The younger line from Johann Petrus Merian (c.1468/1478 – after 1519) is thought to be related, as he was an episcopal steward who also came from Lüttelsdorf to Basel, but whether Theobald (the son) and Johann Petrus were brothers and both therefore sons of Theobald (the father) as tradition claims, is unproven.

In 1624 the Swiss-born engraver Matthäus Merian (a descendant of the younger line) took over the Frankfurt publishing house of his father-in-law Johann Theodor de Bry, and in 1626 he acquired Frankfurt citizenship. After his death in 1650 two of his sons, Matthäus Merian the Younger and Caspar, built up the publishing house under the name Matthäus Merian Seel. In 1687 the publishing house was inherited by a third generation family member, Johann Matthäus Merian (1659-1716), the second son of Matthäus the Younger. Johann's elder brother Carl Gustav Merian was later elevated to the nobility by the Elector of Mainz and appointed to the Privy Council. After Johann's death in 1716 the company was led by his niece Charlotte Maria Merian (1691-1729) until its dissolution in 1727. The Frankfurt family line died with the painter Carl Matthäus Merian (1705-1770), a great-grandson of Matthäus Merian the Elder. The family name is remembered today in Frankfurt's Merianstrasse and Merianplatz, and in Merian School in Nordend.
