In genealogy, what does the term 'removed' mean?

Question:It's a generational indicator. For example, your mother's first cousin is your first cousin, once removed. This is because your mother's first cousin is one generation younger than your grandparents and you are two generations younger than your grandparents. This one-generation difference equals "once removed.

it means you're related only by marriage

Once removed=one generation away;Twice removed=2 generations away; etc.

Your mothers sister' child is your first cousin;
this first cousin's child is second cousin to your child.

This second cousin's child is third cousin to his/her second cousin's child. This second cousin's child is second cousin once removed to you.

So if the generation is the same as this repeats then it is cousin, if the generation is uneven then it is once removed. twice removed and so forth.

"Removed" refers to the number-of-generations differrence between "cousins" from their common progenitor(CP). Example: If your cousin Jane has a daughter, Hadley. Your CP is your grandfather (three generations = FIRST), and your "cousin" Hadley's great grandfather (four generations), a difference of ONE generation, you are FIRST cousins once removed.
Your dad and your uncle (dad's brother) are the same generation. Their children (you and your cousin Jane) are first cousins, or simply: cousins. Your children are first cousins once-removed to your cousin Jane, and your grand children will be first cousins twice-removed to cousin Jane. Jane's children will be second cousins to your children (no removed number because they are of the same number of generations from CP).
So, if you are both three generations from CP, you are cousins; four equals second cousins; five = third cousins; six = fourth cousins; etc. Then, if there is a difference in the number between you and your cousin's generations back to the CP, the lowest number = your ordinate (FIRST cousin) and the diference = the number of times removed.

It means from a different generation: via marriage means nothing in genealogy.
