Hi Sarah, Loren and Duane. I too am a descendent of Cornelius "Niels" Peter Holm. I am actually decended through Henry Paul Holm -> John Witmer Holm -> John Frank Holm -> Verna Adelaide (Wagoner) Holm who was my paternal grandmother.
Sarah, I know you've already visited the mill but this is the info I have on it.
(a.k.a. Krib's, Cole's and A. J. Shants' Mill)
From A History of Vaughan Township by G. Elmore Reaman
Neihls Peterson Holm was a Dunkard and a sailor. Born in Copenhagen, Denmark in Oct.19, 1774, he came to Canada ( Waterloo County ) with the Mennonites from Pennsylvania. He was a sailor in his younger days, and when Admiral Parker, assisted by Nelson, bombarded Copenhagen in 1801, had a narrow escape with his life. After the fall of Copenhagen, he and others like him, took to the open seas, where, for a few years, they led a piratical life. Having eventually landed on the east coast of America, and wishing to avoid punishment for his crimes, Neihls made his escape to Little York (Toronto) under the cover of night. He there married Anna Catharine Phillips of Hamburg, Germany. The couple resided in Markham Township, York County where their children were born.
Although the Eby book states that they came to Puslinch in 1839, it is recorded by others that they were here 10 years prior, when the first small dam was constructed( lot 1- 3rd concession ), on the outlet from Puslinch Lake, used to power a small saw mill . In 1850, a new dam powered the larger saw mill erected at the same time. No longer able to tolerate his land legs, and having built a suitable vessel, Neihls first sailed the waters of Puslinch Lake in 1845. What a joyous occasion that must have been, for Neihls and for all the "sailors" since!
Early assessment rolls of Waterloo County indicate thatamong his neighbours there, were the Pannabeckers Clemens, Baer, Bergey and Ellis families, other surnames common to Puslinch history.
By 1856 a grist mill had been added which was operated by his son Peter Niles Holm ( born March 16, 1811). His wife, Susannah Cober, ( born June 4, 1813 ) was the daughter of Nicholas Cober of Vaughan Township. Peter's son Daniel married Esther Pannabecker and Anna Pannabecker, and farmed lot 6 in the 3rd concession. At about age 35 Peter was ordained as a minister of the River Brethren church, and it is said that his friends and admirers were of all denominations and that possibly when Peter died on Dec.13,1880, he did so without a single enemy.
