Yes.

Whether you treat5 it as 1:1 or 1:n or m:n depends on what you want to use the data for. I'd probably record a table of people and one of marriages. In the marriage table I'd include two foreign keys for the people being married, the data of the marriage and a column for the date the marriage ends (which may be null). I'd probably add another column for the reason for the marriage ending, one reason would be divorce.
