My gg grandfather Joseph Kemp (1799-1850) and son James (1821-1901) had mining and homesteading interests in Wisconsin. Researchers overseas cannot confirm lineage without a place name or parish. Based on logical chronology and name repetitions I have constructed a family tree back to 1750 and down through my Irish Nalty family in the late 1900's. Will share info with anyone interested and hope for confirmation or validation of my findings.
