Hi, I also am one of those Mennonite descendants who settled in Berks County and stayed, intermarrying with the Yoders, Angstadts, Berkys, and Millers. I have a Peter Miller as and ancestor of my maternal grandmother who was an ECK. This is a summary of his life taken from his profile Miller-91725. I found him while looking for the parents of Jacob Miller, his son. And once I added him to my tree my Ancestry Thrulines connections worked. Am interested in whether we are connected.
"Little is known about this Peter Miller.
His son Jacob L. was born in 1806 and baptized at the Old Zionsville, Lehigh County United Church of Christ. Jacob's parents were listed as Peter and Sara Miller. (This would have put this Peter's birth in the late 1700s.)
Jacob married Maria Polly Fenstermacher and together they were the parents of Sarah Miller (1843-1942) who married Solomon Miller (1841-1892). Their daughter was Jane Miller (1870-1929). The descendants of Peter Miller and Jacob Miller were residents of Berks County, Pennsylvania.
In the 1830 Census of Hamburg, Windsor Township, a Peter Miller (age about 45) was head of household in the 40 to 50 age group. Four other males were living in this household: two males were 15-20 yo, and two were 20-30 yo. In addition to one 40-50 yo female (most likely. his wife), there were five other females in the household: Three were 10-15 yo, one was 15-20 yo, and one was 20-30 yo. Peter's age is consistent with his birthdate, as is his wife's. Jacob L would have been 22 at the time of the census and could have been one of the two 20 to 30 yo. Jacob's first child was born about 1833 so this Peter could be his father.
1850 census of Windsor Township in Berks County lists a Peter Miller as 65 yo and Sarah as 34. This Sarah (if the age is correct) could not be the mother of Jacob L since she would have to be at least 57yo (born about 1793) and have been 15 when Jacob L was born. (Jacob would have been 42 in 1850, married with a 7 yo daughter Sarah (1843-1932) and most likely not living at home.) Also living in the household is a Henrietta Shollenberger, 15 yo female. The next household on the Census sheet is headed by Henry Shollenberger (34 yo) and Elisabeth (33 yo), includes Joh J W (8yo male), Mary E (4yo female), and Winfield (3yo male).
A second son, Jonathan, born in 1730 died in 1758. His birth was 22 years after the birth of Jacob L. His mother was listed as Sarah.
A FAG memorial exists for a Peter Miller who died 0n 18 May 1869 and is buried at Saint John's Lutheran Cemetery, Abbottstown, Adams County, PA. His wife was listed as Mary Miller (1790-1874) possibly a second wife."
