Identify this Photographer / Book for me ?

Edit My Images
If anyone can identify either this photographer or his book I would be very grateful.

10+ years back I was shown a book authored by a male photographer.
The photos inside were groups shots of his wife and her 3 or 4 sisters.
He took 1 photo a year of the group of sisters over many years and never identified in the book which one was his wife.
I think the book was around A4 size and the copy I saw was hardback.

I am looking because a friend died recently and he used to really love this book, its driving me mad that I cannot recall who created it, as I cannot search for a copy until I find who its by.
Thanks for any ideas, much appreciated.
