Carol responds:
Or maybe "cousin by marriage" equals "cousin in law." IOW, a man is
your brother by marriage (brother-in-law) if he marries your sister; a
man or woman who marries your cousin would be your cousin by marriage.
So Molly would be Sirius' "cousin by marriage" simply by marrying
Arthur, Sirius' distant cousin. There would be no blood rellationship
between Molly and Sirius either way.

If Molly's cousin married Sirius' cousin, his cousin would have to be
on his mother's side of the family unless Molly's cousin is Lucius
Malfoy, Rodolphus Lestrange, or Ted Tonks. (I know that Sirius's
mother's painting screams about "her" family, but unless she was also
a Black before her marriage, the Black sisters are her husband's
relatives, not hers.)
