Can I marry my grandmother?
Looking through the thread about Crusader Kings on a CK Reddit, I ran into the following throwaway comment:
The genocides, the murders, the marrying your grandmother and having kids........beautiful!
I know we discussed other weird marriages in this game here (" Is marrying my own sister a good idea? "), but can the game actually be practically played in a way that you can marry your grandmother and have kids? How?
Best Answer
In the best possible case, this would be the progression: Your grandmother, Alice, marries Bob at the age of 16 (minimum age) and has a child, Charlie, when she turns 17 say. Charlie marries at 16 and has a child at 17, you. At this time your grandmother Alice is 34 years old. By the time you turn 16, your grandmother will have turned 50. The game makes women completely infertile at 45 (see CK2 wiki), so you would not be able to have children.
Even if the people in the chain somehow managed to have children immediately after marriage at 16 (practically impossible) that would still make your grandmother 48 when you're first eligible to marry her, past her child bearing years.

Can I marry my Grandmother sister son?
Yes. The daughter is his second cousin, and marrying second cousins is not prohibited anywhere in the United States. Other countries may have prohibitions against marrying second cousins, however. The guy and the daughter share a set of great-grandparents, who are the parents of the grandmother and her sister.Can you married your aunt?
Such a marriage may occur between biological (consanguine) relatives or between persons related by marriage (affinity). In some countries, avunculate marriages are prohibited by law, while in others marriages between such biological relatives are both legal and common, though now far less common.My GF Is Old Enough To Be My Grandmother | LOVE DON'T JUDGE

Answer 2
If you extend the definition to anyone who is your biological relative and also your grandmother by law, this becomes possible. If your dad marries a woman, has two children, you and one girl, then divorces her and marries the child while you marry your mother, your sister becomes your step mother, and her mother is your step grandmother, as well as your wife and mother.
However, divorces generally aren't that practical and usually completely tear apart the two families, but if instead your dad has you, and another woman somewhere else has a daughter at <20, you can do the same age swap as above and still end up being married to your step-grandmother.
