What's Your Ancesteral Name Number?

It has been quite a while since I've posted anything.  Life has just kept me away but this seemed like an easy way to get back up and writing, so I thought I'd take on Randy Seaver's SNGF task of determining what percentage of your family tree do you have complete.

Here is my chart:
 

Generation	Number	Found
Parents	2	2
Grandparents	4	4
Great Grandparents	8	8
2nd Great Grandparents	16	16
3rd Great Grandparents	32	22
4th Great Grandparents	64	26
5th Great Grandparents	128	24
6th Great Grandparents	256	12
7th Great Grandparents	512	13
Total	1022	127
That works out to be about 12 % found or 895 missing

This kind of depresses me.  It seems like when I look at my tree and all of the data and people I do  have in it, my percentage would be bigger than 12.   I do really well right up until my 3rd great grandparents, and then there are big gapping holes that lead to no where.

My weak "branches" are primarily on my mom's side of the family.  They happen to all come from the Netherlands.   Many of these relatives stayed in Holland.  I currently don't have the skill to tackle this endeavor.  I need to learn how to navigate the Netherland records as well as how to use the translator software to begin to make a dent.  If anyone out there has some tips or specific suggestions on how to begin, please send them my way.  The Dutch family names that I need to explore are:
DeVisser, Wisse, Vannxen, and Misjelje.

On my father's side of tree I am missing one set of 3rd great grandparents, which I honestly think I could fill in today if I just spend a little time.  I know that tree has been researched and documented.  I just need to go through those documents and insert the information into my tree.  That never seems like much fun when the information is known and you are just adding to your database.  I like the thrill of the hunt -- I just have enjoyed it being in English.

IK veronderstel dat het tijd is om te leren een beetje Nederlands!!
