Christian Henrich and Maria Margaretha Henrich had at least seven children:

1. Christian Henrich,Jr. married 1st to Magdaline Bervertz on September 20, 1767, the sister-in-law of Christopher Eckenrode/Eckroth's sister. Christian Henrich Jr. then married 2nd to Widow Anna Mary(Marie)Neuer Eckroth (Widow of George Eckroth(2)of Lynn township)married 20-27 November 1807 marriage was solemnized at the Goshenhoppen Catholich Chapel on 31st of July in 1808. (WK-book, page 403)

2. Elizabeth (Henrich) Married 1st May 16, 1773 George Jacob Riffel who was shot and killed in May 1775 by Daniel Starr; Elizabeth's 2nd Marriage was to Andreas "Andrew" Greth/Grett/Gredt Andrew Grett Jr. on November 17, 1777. Andrew Grett Jr. was born on July 17, 1755 and who died October 4, 1811, age 56 years, 2 months and 15 days.

3. Philip Henrich married May 16, 1773 to Elizabeth Weibel; probably the sister of John Weibel who married Philip's sister Anna Margaret Henrich (Goshenhoppen Registers, page 105, "Records", Volume 3, page 382). (WK-book, page 403) They had children: Philip Adam Henrich, he is buried at Old St. Henry's cemetery, Moselem PA.

4. John Adam Henrich married Marie Barbara Spring. They had seven children and lived near Pine Swamp Rd. in Albany Township, Berks County, PA. Later moved to another area of PA. (WK-book, page 403)

5. Mary Magdalen (Henrich)married June 7, 1778 Henry Finck (Goshenhoppen Registers, Page 109; "Records", Volume 3, page 386). (WK-book, page 403)

6. Eva Mary (Henrich) married about 1768 to Adam Stahler (Goshenhoppen Registers, Page 36, and 64; "Records", Volume 3, pages 313 and 341). (WK-book, page 403)

7. Anna Margaretha (Henrich)1st married November 20, 1775 to , John Weibel by whom she had a daughter; Mary Margaret Weibel- born on August 16, 1776. (Goshenhoppen Registers page 60 and 108; "Records", Volume 3, page 337 and 385). John Weibel died between August 1776 and April 27, 1779, the date of Anna Margaret's (Henrich's) second marriage to Christopher Eckenroth/Eckenrode. I have not been able to determine what beame of their daughter, Mary Margaret Weibel. At the time of her mother's marriage to her second husband Christopher Eckenrode; Mary Margaret Weibel would have been almost 3 years old. Assuming that he was still living at that time, I have no doubt that Christopher Eckenrode would have welcomed her into his household in this census. For this reason, I believe she may not have survived to maturity, dying before 1790. (WK-book, page 403)

Please Note: In Kreis Neuwied Rheinpfalz,Germany, the name "Bieber" appears in the IGI-index.

Please Note: the Origin of the Surname meaning would be of that of "Bewaehrt"; meaning tried and true or proven trust worthy.

Please note of Bavier name Buer: The house passed different names over time. In the 12th century, it first appears as Erkerode (The ending -rode points to a courtyard on cleared land). Then in the 14th and early 15th century as Schletzgut or Schletthausen after the then owners, the lords of Schletz (Sletz). When the house came to the Lords of Buer in 1515, they named it after their name, d. H. after her former headquarters Burg Buer in Gelsenkirchen-Buer. Towards the end of the 16th century, however, the family "translated" their name into High German into Bawyr, Bavier, Baur or Bauer, so that Haus Buer became the home of Bavier. This name has been preserved until today and can be found eg. B. in a Erkrather street name (Bavierstraße) again.
