Give us the name and I'll have a look!
Remeber as Tati says, to look through the COMPLETE indexes quarter by quarter, rather than the partial ones on the database.
ANd also remember that ANcestry's indexing leaves a lot to be desired. Always remember you are looking for an alphabetical list, so there will always be a page where the name you are looking for will be alphabetically (unless very rarely by chance it does occur exactly at a page break), so dont believe it when it comes back with an apparent 'missing' quarter or 'no match'
The best way to get round this is to try a name nearby yours in the alphabet, and then use the green arrows at the top of the sheet to move to the correct page.
But I will willingly have a look for you. Or if you want me to find the one that you are definite about then tell me that one, and maybe I can find where the hitch is!!!!
