Is marriage between two step siblings legal in the US?

Boston, MA |

I'm doing research for a book and was wondering if the characters who aren't related in any way by blood and who are of legal age can marry.

You would have to research the answer for each state. In Mass. the level of affinity provisions disallowing certain marriages do not include a prohibition of marriage between adults who are related to each other only by the marriage of their parents.

Sections 1 and 2 of the marriage statutes are where the answer to you question appears in Mass. law.
