Maths Challenge #8 – Family Occasion

'It was a wonderful party,' said Lucilla to her friend Harriet.
'Who was there?'
'Well - there was one grandfather, one grandmother, two fathers, two mothers, four children, three grandchildren, one brother, two sisters, two sons, two daughters, one father-in-law, one mother-in-law and one daughter-in-law.'
'Wow! Twenty-three people!'
'No, it was less than that. A lot less.'

What is the smallest size of party that is consistent with Lucilla's description?
