The earliest record of the Nolder name in England seems to be about the year 1100 so perhaps the family arrived at the time of the Norman conquest.Some researchers believe that the name was originally Alder and over the years changed to Nolder.
I believe that the family found itself on the wrong side in one of England's little internal wars and fled to the continent at the time of "The flight of the Earls".As the men were mostly soldiers and some with minor Titles they found employment with the rulers in such countrys as France, Prussia and Austria.
My own branch of the family found themselves in Prussia and fought in the Napoleonic wars both with and against England.
In that time period between 1750 and 1820 the family began to migrate back to England and eventually the USA.A John and a Nathaniel Nolder are found in the USA from about 1780 on and as I said in my first posting a Mary Nolder appears much earlier, probably due to the reason the family fled England in the first place.
My documentation of the family is limited to the period that finds them in the New York area of the USA.Others have documented the branch of the family that settled in PA and I have yet to find documentation on the branch that are found in New Orleans in the 1870 federal census.
As I said much of the English/Prussian history consists of family legend and relics of Napoleon's wars.Familysearch.com and Ancestry.com both have limited Nolder data and are worth visiting.
