Following biography from familysearch by Barbara/Robert Beers:

Johann Adam was born to Philip Frederick Seegmiller and Magdalena Huber on 5 September 1807 at Richweiler, Zweibrucken, Bavaria, Germany. It was during the time of the great triumphs of Napoleon Bonaparte. Conditions then were pretty rough all over Europe. Adam Seegmiller and his brother Jacob, having set up a partnership, decided to go to America, where they hoped to find safety, security, and fortune. They settled, with other Germans, on the shores of Lake Huron at Goodrich, Ontario, Canada.
He and his three brothers came from Germany to America but went on to Canada, settling in the Ontario province. There is a history of this.
It is thought that he married Anna Eva Knechtel in Germany first. [They actually married 24 August 1834 at Stratfird, Perth, Ontario, Canada. Their children were all born in Canada.]
There was a boom that struck Stratford, Canada. Johann was the first Treasurer for Stratford, Ontario, Canada. Speculators had come in and with promises talked Johann Adam into signing their notes and taking his farm lands as security. The speculations failed and left him financially ruined. The shock was so great that he died of a broken heart.
Some genealogists feel the Seegmiller's may have originated in Switzerland. Country borders do change. For information: The German spelling of Seegmiller is Seegmuller, with two dots over the "u." The French spelling is Segmiller. Older records show Johann may be spelled as Jean (French), and as John (English).
Historically, the village of Rieschweiler was part of the Duchy of Pfalz-Zweibrücken. In 1792, it was occupied by France and in 1801, was fully incorporated into France as part of the Département du Mont-Tonnerre (Donnersberg). So technically, Johann Adam Seegmüller was born in France in 1807. It was not until 1815, that the territory was awarded to Bavaria, and not until 1870 that it became part of Germany.
