More on Family History

Here's my thinking through the problem of verifying information in a GEDCOM. I think I must be making this harder than it is.

So there are 2 problems:

1. Identifying the ancestors I want to verify. This is neither every one in the GEDCOM nor everyone in the book of remembrance. It would also be nice to verify an ancestor and his/her spouse at the same time. There are around 200 people I'll need to look at.
   
2. Correcting the information - this includes birth, death, and marriage dates plus adding in the references where the information came from.
   

Possible solutions:

1. In PAF, I could generate a list of ancestors, print it out, and go through it, checking each person and their marriage on the computer as I come to it.
   
2. The problem with working off the PAF list on the computer (and not printing it out) is that while I can edit personal information, I can't edit the marriage date. I guess I could go through the list and verify all personal information, then do a second pass and verify marriage information and add in references.
3. Print out the family group sheets and go through them with a red marker. Then go through and enter the info into the computer. This could use a lot of paper.
4. Create a GEDCOM of just the people I want to verify, then go through it. The disadvantage with this is that the information will have to be merged back into the original GEDCOM file and I don't know how bad that would be.
   
5. Check out other free family history programs. I know there are some that are database backed, so in theory I could do the query and get a useful list of people. The only issue is that I want to make sure that I can get a GEDCOM back out. I can't imagine that I couldn't, but who knows.
