I know a marriage that I always thought was a little peculiar.
He is a 20 year old from Pennsylvania. She is a 42 year old from Jamaica, the Caribbean island.
She has 6 children from a previous relationship. Her oldest girl is 16. The children were being cared for by her mother in Jamaica while she came to the United States to work and send money back.
When these two got married they sent for all six children. They had one child of their own, a daughter.
I don't want to say more on fear that they are recognized, but that was one coupling I could never understand.
