Cousin Joe was born in 1907.

Cousin Jody died in 18 August 1975 of cancer.

Cousin Joe Pleasant's birth name is Pleasant Joseph.

If your cousin's parent (the one who is married to your mom or dad's brother or sister) has siblings with children, then those children are your cousin's cousins, too, and are not related to you.

For example, your dad has a sister who married Joe, and she and Joe have a daugher named Jane. Joe has a sister, Mary, who also has a daugher. Joe's daugher is Jane's cousin, but is not your cousin because Joe's sister is not related to you.

Joe is my cousin. (just a relative)
