William and Anne McIntosh Clynch

I am trying to find info on William P.Clynch who Married Anne McIntosh in Minnesota.
The census says William was born in Ia. and Anne was born in Renville Co. Mn. to John and Caroline Falkel McIntosh.
They lived in St. Paul in the early 1900's. He was a Police officer out of the Margaret Street Substation. Anne's, Father John was a brother of my Greatgrandfather.
Any info on the family would be greatly Appreciated.
Thank You.
Louise
