The Verger, his wife and their apostrophes

If the wife of the Verger has a favourite pew is it the ‘Verger’s wife’s favourite pew’? I think it is, but the double apostrophes make me nervous. Help in the comments would be much appreciated.

For those wanting some more in depth reflection on this sunny (here at least) November afternoon (here at least) have a read of ‘Betraying Jesus‘, an article by Jim Wallis.
