Tambon creation from more than one parent Tambon

Another statistical fun with the subdistrict creations made possible with the processing of the Royal Gazette announcements into XML. In most cases, a newly created subdistrict (tambon) is created by splitting one subdistrict, so some of the muban of the parent subdistrict get reassigned to the new subdistrict. However, more rarely muban from two subdistricts are placed together to form the new subdistrict. The highest number of parent subdistricts I came across so far is four. In fact, the numbers are as follows:

• 1 parent: 1887 times
• 2 parents: 128 times
• 3 parents: 32 times
• 4 parents: 6 times

All of these five special cases originate from before 1990, and as it's just so few I list them in detail as well.
