Your third cousins are those relatives who share a great-great-grandparent with you. They are the children of your parents' second cousins and the grand children of your grandparents' first cousins.
they're your cousins
Their brothers, sisters, parents, cousins.....
The cousins of your in-laws are not related to you and neither are their parents. However, the parents of your spouse's first cousins are your spouse's aunts and uncles, and thus your children's great aunts and great uncles.
Your child and your great nephew's parents would be first cousins. Their children would then be second cousins. And if they have children, they will be third cousins.
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.
Depends on how closely related they are. Parents being brother and sister is real bad. Parents being cousins is only a little bad. Parents being further apart than cousins no one really care about.
Your great great aunt is the sister of one of your great grandparents.Her grandson is second cousin to one of your parents, and your second cousin, once removed.
The children of your grand uncle are First Cousins to one of your parents, so you and they are First cousins, Once Removed.
The correct spelling of the plural noun is "cousins" (specifically first cousins, children of your parents' brothers and sisters).
