It was common. In history many people married very close family.
Your parent's first cousins are your "first cousins once removed". When referring to cousins, the number indicates (first, second etc) indicates the number of generations since you had a common ancestor. For first cousins the common ancestor was two generations previous (i.e grandparents), for second cousins it was three generations and so on This only works if the cousins are in the same generation. Therefore the 'removed' indicates the number of generations separating the people concerned. When you were born, you were one generation removed from your parents first cousins i.e you were their 'first cousin once removed'. The child of your parents cousins are your second cousins. It may be easier to understand this with diagrams rather than with words.
They would be second cousins, once removed. The descent is from a common ancestor. Thus 1st cousins share a grandparent as a common ancestor. 2nd cousins share a great-grandparent as an ancestor. If the descent from the common ancestor is not an equal number of generations, the inequality is expressed as 'removed' from the oldest generation being compared.
Two people who share the same great great grandparents are third cousins. To find a cousin relationship, find the common ancestor. If common ancestor is grandparents, they are 1st cousins. If common ancestor is great-grandparents, they are 2nd cousins. If common ancestor is great-great-grandparents, they are 3rd cousins.
If two people are first cousins, the children of one are second cousins to the children of the other.
Your sons children and your daughters children are First cousins. The idea is that First cousins share a grandparent, second cousins share a great-grandparent, third cousins share a great-great-grandparent, and so on. The degree of cousin relationship i.e. "first," "second," etc. is used to denote the number of generations between two cousins and their nearest common ancestor. Now, a term "removed" is used to refer to the number of generations separating the cousins themselves. So your first cousin once removed is the child (or parent) of your first cousin. Your second cousin once removed is the child (or parent) of your second cousin. And your first cousin twice removed is the grandchild (or grandparent) of your first cousin. etc. Thus in this case they are first cousins once removed.
