Recently I asked the owner of a tree on Ancestry how they were related to my gggrandfather..This is the reply.......... my wife Susan relationship to William....William is Susan's 3rd cousin 3 times removed wifes aunts husbands great grand nephews wife's grandauntshusbands father.
The tree owner is married. His wife is Susan. Susan is the one who is claimed by the tree owner to be related to Ringrose’s great great grandfather. The relationship is claimed to be : 3rd cousin, 3 times removed.

Susan has an aunt.

Aunt is married. The ‘connection’ is via that Aunt’s husband, who is an INLAW, ie not a relative, so obviously
William is NOT a relative of Susan.

Anyways, as to that Aunt’s husband, well, he has a great grand nephew.
That chap (the great grand nephew of the husband of Susan’s aunt) is married. This next ‘connection’ is also via an INLAW connection, so again,
William is NOT a relative of Susan.

Anyways That great grand nephew’s wife has a grand aunt, who is married. This next ‘connection is also via an IN LAW connection.
So, again, William is NOT a relative of Susan Anyways, The grand aunt’s husband has a father. That father is William. Ringrose asked how that William was related to the tree owner. (As a chap by that name is Ringrose’s great great grandfather).
Surely,

The tree owner has successfully demonstrated that their William has a daughter IN LAW who was NOT related to Susan, who is the wife of the tree owner.
I doubt any software actually reads William is related to Susan because (tree owner's) " wife's aunt's husband's great grand nephew's wife's grandaunt's husband's father" is William
