The Watson-Wentworth and Finch Families Charles Philips (1708-1747)

The picture has something of this: people, group, woman, wear, dress, child, many, veil, man, girl, wedding, castle, outfit, royalty, costume, ceremony, model, home.
Perhaps it’s a painting of a group of people standing in front of a building with a dog in the foreground and a man in the middle of the picture.
