🔼The name Mareshah in the Bible
The name Mareshah (spelled מראשה in Joshua 15:44 and מרשה everywhere else) belongs to two men and one town mentioned in the Bible.
The town called Mareshah was a town in the lowland of the territory that was allotted to the tribe of Judah (Joshua 15:44). It was fortified by king Rehoboam of Judah (2 Chronicles 11:8), which proved convenient for the later king Asa, when Zerah the Ethiopian mustered a huge army and marched upon him at Mareshah, or more specifically: at the nearby valley of Zephathah (2 Chronicles 14:9-10).
The even later king Jehoshaphat of Judah foolishly allied himself with king Ahaziah of Israel, but was sternly told off by the prophet Eliezer, son of Dodavahu of Mareshah (2 Chronicles 20:37). The prophet Micah warned that YHWH would bring the possessor (ירש, yarash) against Mareshah (Micah 1:15).

🔼Etymology of the name Mareshah
The name Mareshah consists of the preposition מ (ma), which denotes an agent or place of the part that follows.

For a meaning of the name Mareshah, NOBSE Study Bible Name List goes with the root ראש (ro'sh) and reads Summit. Jones' Dictionary of Old Testament Proper Names goes with the same and suggests the rather elaborate That Which Is At The Head.
BDB Theological Dictionary, timid as ever, gives no hint to preference and lists our name alphabetically under מ (ma) in stead of under a specific root.
