Hi Lindsay,
Have you looked at creating a Unique List in the Address column. If the
address is over more than one column, then concatenate them into one column,
and on this column use Data Filter Advanced, where the List Range would be
the concatendated column, and make sure you Tick the Unique Record Only
option.

Hope this is useful

John

siblings and they bear the same address. Is there a way that I can do to only
mail merge to one household instead of 2?
