Muban names with or without Ban?

Most of the time when I get around the name of a muban it is preceded with the word Ban (บ้าน, House). However, if this Ban is actually part of the name, or if it is just a remnant of the term Muban (หมู่บ้าน) - literally meaning group of houses - is something I am still not sure about.

Why I wonder - the village list I found earlier does not include the Ban except for few instances, and also occasionally Royal Gazette announcements have a double Ban - e.g. the creation of Muban Mai Ruam Charoen (บ้านใหม่ร่วมเจริญ) in Wang Ngio subdistrict, Dong Charoen district, Phichit province in end of 2006 (Volume 124, Issue พิเศษ 8 ง, Page 145-148), in which is reads

แยกหมู่บ้านบ้านใหม่ดงเจริญ หมู่ที่ ๖ ตำบลวังงิ้ว จัดตั้งเป็นหมู่บ้านใหม่อีก ๑ หมู่บ้าน
ชื่อหมู่บ้านใหม่ร่วมเจริญ โดยตั้งเป็นหมู่ที่ ๑๑ ตำบลวังงิ้ว

which means Split of village Ban Mai Dong Charoen, Village 6 of subdistrict Wang Ngio, to create one new village named Muban Mai Ruam Charoen, and make it village 11 of subdistrict Wang Ngio. Too bad the district Dong Charoen is missing in that Excel sheet, so I cannot check if village 6 there has the Ban in its name. But most other similar announcements have a only a single Ban.
