I know it's about 3 years after your post, but I started researching the Kestenholtz/Chestnutwood family recentely and found this for your Jacob:
"KASTENHOLTZ Sr, for 17 years a resident of this county, died at the home of his son, Jacob KASTENHOLTZ Jr. Friday p.m., Sept. 24, after a long and painful illness. Mr. KESTENHOLTZ was born at Nortland, Switzerland, June 2, 1824, and had reached the age of 85 years. He came to Crawford when 18 years of age and at 20 married Rebecca HEATON to whom were born 12 children, of whom are left to mourn, Mrs. Hannah BOSTON, Hartford City, Ind., Mrs. Kate HELMKEY, and Mrs. Emma SHANNON of Colida, Ohio, Mrs. Elizabeth SIERFOSS of Gladwin Mich., Mr. Wm. KESTENHOLTZ, Omaha, Neb., and John and Jacob Jr. of Roscommon. The sympathy of the large circle of friends is with the afflicted family. He was buried in the South Branch cemetery, Rev. J. H. CORNELIA officiating at the funeral service. (30 Sep 1909)
-SOUTH BRANCH NOTES. The funeral of the late Jacob KESTENHOLTZ was held at the home of his son Jacob KESTENHOLTZ, Sunday afternoon. The services were conducted by Dr. CORNALIA of Roscommon. (7 Oct 1909)"
This information comes from the Grayling, Crawford Co., MI Newspaper Avalanche. You may have seen it already, but I'll send it to your e-mail address as well.I'm curious to see what his relationship is to the Jacob Kestenholtz born much earlier (October 27, 1700) who was also born in Switzerland but came to the United States before 1726.
