Oh, by the way, your husband's sister-in-law is my cousin, too.

Today's adventure started out with an obituary.  Nothing unusual so far.  As I entered locations of the children I realized the one daughter (my distant cousin) was listed without a husband.  I knew she was married at one point so either they were divorced or he passed away.  I googled him and found his obituary.

As I have pointed out before, I list parents and sometimes siblings from obituaries as I seem to be related to over half of the people in the county.  I double checked his siblings against my database.  There's a possible match.  Richard H.

I check more details.  It is a match.  But why is Richard H. and his wife listed in my database?  He has no parents listed, no children listed.  I click on his wife.  OMG.  His wife is my 5th cousin. 

Maybe I'm related to two-thirds of the county!

(The other brother, Ronald, is not in the database...yet!)

I wonder if they are cousins to each other...

William, a 4th cousin 1x removed, married Ruth.  After I entered Ruth's information I noticed have her name twice in my database.  I check.  Sure enough.  The two Ruth's are the same.  Ruth is my 6th cousin.  Just for fun I ought to check and see what cousins they are to each other since they are in the same branch of my family.

As I check I discover I am related to Ruth twice.

I am pretty sure William and Ruth are cousins. 

Ruth is his 6th cousin.  I wonder if they knew...
