To add or not to add "DE" in a surname?
Yolanda:
I guess the answer to your question depends on the software that you are using. I use an online database called The Next Generation that allows you to enter the "DE" or "DE LOS" or "DE LA" in a seperate field from the main surname such that when you search or sort by surname these are not taken into account.
When I import the GEDCOM from this software into PAF, I get the same problem that you do... a bunch of people end up under the letter "D" and I forget to look for them there.
