I appeared ruder than I meant to be - however there is a serious point in how and where people place their queries - every so often there seems to be a small batch of inappropriate postings (often it seems German-American), I wonder if a quick search for 'German' is turning up the Manx parish name and posters just plough ahead, once one such name is posted subsequent searches attract further posters until lack of any response moves the entries in the search engines down too far to be selected. As an example look at some of the posted replies when non-detailed subject lines (eg Familiy search!) have been used - they can only come from search engines giving a list of pages followed by no subsequent examination of the board by the poster - similar things seem to happen when UK regiment names get mentioned.
The point of my comment was that it would be easy to swamp a Manx thread with non-Manx postings hence the use of 'fly-posting' ie placing material without regard for its position.
Sorry for the delay in replying to what is now probably a cold thread but am just back from Peel
Re movement into/out of the Island - yes there was some pre the end of 19th century when mass movement around Europe became more commonplace - but most of the families (eg the Geneste's, dela Prymme's etc are traceable in the records; the major influx of german names came with internment in 1914 but I think all left the Island post war.
