History of German small town of Angloh?

Question

I found the town of Angloh in Germany but nothing is left of it other than a spa.

I tried searching for weeks throughout the web but couldn't find anything about it other than coordinates.

How do I find established and history on a forgotten town like this?

Full Name (see definition): Angloh Primary Country Code (see definition): GM (Germany) First-order administrative division code (see definition): 02 (Bayern ) Region Font Code (see definition): 1 (Americas/Western Europe) Unique Feature Identifier (see definition): -1740505 Unique Name Identifier (see definition): -2437399 Latitude in decimal degrees (see definition): 48.333333 Longitude in decimal degrees (see definition): 13.283333 Latitude in degrees, minutes, and seconds (see definition): 48° 20' 00" N Longitude in degrees, minutes, and seconds (see definition): 13° 17' 00" E Military Grid Reference System coordinates (see definition): 33UUP7277454774

Answer 1

Technique
Generally when you cannot find information on very small or insignificant placenames, you research nearby larger places (because events may apply to a larger area) or the next placename in the hierarchy. You may even get lucky and find passing references to your main interest that weren't directly searchable.

Scope
Angloh (var. Angerloh) is officially part of Kirchham, so searching the history of that city would be first. Also Landkreis Passau and its predecessors and Bavaria.

Resources
Don't restrict yourself to on-line searches. Check library and archive catalogues for hard-copy histories and digitized materials that may accessible but not searchable.

Remember that much more will be available in the local language and in the actual vicinity. "Bayerischer Landesverein für Familienkunde e.V." (BLF)" has publications and forums that may be relevant. A Worldcat search returns, among others, "Kirchhamer Heimatbuch: auf der Grundlage der Chronik von Kirchham bis 1945" and "1200 Jahre Kirchham : Zu d. Feierlichkeiten vom 2.-10. Juli 1977." At GoogleBooks: Statistische Beschreibung des Bisthums Passau, 1867, p. 71 says that the parish of Kirchham includes the village of Kirchham (41 houses with 325 inhabitants), and, outside Kirchham, among others, the place "Angerloh" (1 house with 9 inhabitants).

Final comments
Angloh may always have been small, and a local name for a crossroads or a farmhouse. Or it may have been a thriving village or town before war or pestilence depopulated it (a frequent occurrence in Bavaria). If the former, you may never get much additional information.

Also, by definition, a surname referencing a past residence was acquired AFTER moving elsewhere. Depending on the era that occurred, there may not be a record documenting it. If the surname is actually a farm-name, then any family living there may have taken on (or been known as) that name, without necessarily being related to the previous residents.

Answer 2

bgwiehle provided a great answer that might help with research for other small places as well.

Some additions to Angloh. GOV (an gazetteer) lists Angloh as an “Einöd”. This means by definition just one or two residential houses, see e.g. German Wikipedia. Such places were (and are) common especially in southern Germany. Sometimes they vanished with the death of the last one living there and the name referred to a place without any housing until someone else settled there later. There might also have been several places named Angloh and there is no written tradition for the others (please note that most German surnames date back to the medieval ages).
