There are two friends, they are not related. Each has a daughter. Their wives are dead.

Each man marries his friend's daughter, and after a while, both couples will have a child (a daughter).

What is the relationship between the two babies?


1 Answer 1

  1. The first baby would be a daughter of the daughter of the second man - his granddaughter. The second baby would be a daughter of the second man.

  2. Therefore first baby is niece to the second baby. Similarly she is an aunt for the second baby.

  3. Starting from this point one can find out that first baby is step-granddaughter for herself. Therefore first baby for the second baby is step-great-granddaughter and step-great-great-great-granddaughter, and step-great-great-great-great-great-granddaughter, and so on. The same is true for the first baby. Therefore first baby for the second baby is also step-great-grandmother, step-great-great-great-grandmother and so on. (But I'm not a native language speaker and not sure how correct it is to use here prefix "step" only one time per word.)

  • $\begingroup$ After one "grand", we use "great"s in English: father, grandfather, great-grandfather, great-great-grandfather, etc. I don't understand the relations here, so I'll let you fix it. $\endgroup$
