The name Dendtler can be spelt i many ways, but pronounced only in one way. (as far as I know) A family in Aarhus, Denmark was registered as DENDLER, DENTLER, and DANDLER. (1834/1845)
The most commen form in Danmark is DINDLER after my great-great-grandfather Johan Carl Friedrich Dindler [born about 1817 in Spandau, Preussen-Brandenburg] married to Anne Sophie Johansen may 6 1848 in Odense, Denmark. In archives on Odense from that time, there is also a person named DÆNDLER (DAENDLER). The Dindler version does also exist in USA, probably all relatives to me (I don't know that for sure - yet). A single one found on a website in South Australia.
Stewart from Virginia (with danish ancestors from St.Croix) couldperhaps be related to Bernhardt Frederik Wilhelm DENTLER borndecbr 18 1832 in the city Slesvig (- now in Germany named Schleswig) His parents were Heinrich Joakim DENDLER (sergeant) and Cathrine Petersen.,
searching telephonenumbers on (yellow pages in Denmark) http://www.krak.dk/http://www.krak.dk/ and http://www.degulesider.dk/http://www.degulesider.dk/ gives (5.3 mio. inhab. in Denmark and half as many telephones) 4/4 Dændler (same as Daendler in Denmark) 15/17 Dindler 0/1 Dendler 1/1 Dendtler (who is living on the present danish border to Germany. As the main part of Schleswig-Holstein is no longer a part of Denmark, most of the Dentler/Dentlers in the area can be found on the german side of the border.
http://www.teleauskunft.de/NSAPI/http://www.teleauskunft.de/NSAPI/ choose Telefonbuch search for DENTLER (or the like) under Name oder Suchwort and perhaps only SCHLESWIG or FLENSBURG (the biggest old danish cities in the lost land).
The name Dendler must be of german origin. [It is NOT danish, and it "sounds" german to me (with my danish ears)] Searching the net you will find (only few) Dendlers (and alike, but) in many parts of german speaking areas from Swiss, Rheinland, Sachsen and so on. It would be my guess, that these people are not all part of one family, only that they were all once germans. (Some of the older ones (17XX)in USA is from Pennsylvania; There are no Dendlers on US list of "Hessians"(= german soldiers serving George 3 in the War of Independence ) )
I have not any ideas of how your forfathers came to England, but it seems not unlikely, that it was from the Hannover area. (Former connection to England.)
If I find anything of relevance, I'll let you know. If you find anything on Dindlers/Dendlers in Prussia, please tell me.

-------- Danish/German archives ---------------------- Schleswig-Holstein was a part of Prussia from 1864. The archives for Schleswig-Holstein wassplit between Denmark and Germany after the return af the northern part of SCHLESWIG to Denmark. I guess that any information possibly relevant for you must be obtained from Schleswig-Holstein, Germany or some other german archives (Germany is a federation and german archives are regionally distributed.)
