The Frederick Rex / Lawerance Gustafson Family Tree

The surnames that I am researching are Gustafson, Rex, Crouse,Hulsizer, Westerlund, Shimp, Booth and Hale. All these families lived their lives in the Penna area. Mostly from around Bradford or shippenville. The Hulsizer family was at one time from Emmolton Pa in Clarion County. Oscar Frederick Gustafson was born in Sweden, not sure where exactly but died in Bradford Pa. He and Emma Crouse were married in Ludlow Pa. She was born in the year of 1888. She died in Bradford Pa in May 1958.
I am also researching Dumont from Canada near the Montreal area. The Shimp and Hale union took place in 1902 and they lived in Shippenville Pa. I believe that Booth was the name of Robert Shimp's mother.
That is about all I know for now. Any help you could give would be greatly appreciated.
Thanks Sandy Dumont
