What is the record for the most living grandparents?

Question:

What is the record for the most living grandparents?

How to find out about the Ginness Book of Records?

Best Answer - Chosen by Asker: My nephew, born last year, had (and still has!):

4 out of 4 living grandparents
6 out of 8 living great-grandparents
1 out of 16 living great-great-grandparents

I'm sure there are people out there who have had more living grandparents than my nephew did.
