Do not know if this is going to reach you or not as this site is so old but here goes. We have Dingmans in our family that came from Wainwright. Actually our family is from Wainwright. My Grt. Aunt Hazel Dean or Tine(this would be Hazeltine but not the Dean) married Nathan Dingman. His dad farmed in the area. Nathan was the only child we know of. They were married in either Wainwright or Edgerton and had 4 children - Lorne, Ruth, Joyce and June. We have more family history from there. Also I might be able to direct you to another site. Hope this matches.
