Show more than one spouse in Book of Ancestors

[Mick O'Halloran]

I would like to show both of my GG Grandfather's wives. He married first and they had a child. The wife died and he married again and had several more children. I am making a book for the family and would like to have both marriages covered. I can mention the first wife and child in a note field but this does not include them in the indexes, etc. What is the best way to include both wives?
