I have no connection to the "van Dorn/Doren/Doorne" name or its variants.
Through my mother I am of Dutch descent, from an Ancestor who bore arms in the 1500's and is proven that I can apply through the Netherlands for those arms.
I am a student of Dutch and Belgian Coat of Arms, and have contributed much to families in thier research without charge. Some are now in the process of writing family history books or updating their websites. I have even corrected a few experts.
I simply stated (1) There are many "van Dorn + variants" families, which agree with. (2) There are many "FAMILY ARMS (familiewapens)" for those bearing these names, which you do not contest.
It is always up to the individual to do, or have someone research their genealogy. Only this way, should you prove a connection to a coat of arms, NOT BY HAVING A LAST NAME CONNECTION.
Let me correct you here, although genealogy in the Netherlands actually seems to be a combat sport one should not say the vast majority of the Dutch population does Not have a coat of arms. One should say "Through the centuries of the BUTCHERING of names in the Dutch language many Dutch people are unaware that they are connected to an ancestor who bore arms." I should know I help people everyday may a discovery!
The second correction is that many poor farmers and labourers came here to make a better living, but because you were one them it was still possible they may have had arms!
If you hany doubts of my family connections to the Netherlands, to coat of arms, proof you only have to watch Netherlands channel 2 this DECEMBER which will feature the research of my family and a book due out in the next few months! The faily is documented in the 1930's de Navrosher and recentlty de Nederlanshe Leeuw(2007)!
Now how may I be of assistance to you and your reseach?
