Hey Bob, I don't think there is a "Lakeview Cemetery" in Dakota County, Minnesota. I checked two references and could not find a cemetery by that name. There are two Lakeside Cemeteries, one in the city of Hastings, and one in Randolph Township. There is also a Lakeville Grove Cemetery in the city of Lakeville. All three have been transcribed. You can view the list of burials via the Dakota County Genealogical Society website. I did not see your Rufus & Harriet DUNHAM listed. There are some DUNHAMs buried at the Lakeville Grove Cemetery, but not the ones you seek. Happy hunting.
