SIMON BOPP ca. 1811, Germany (Baden)
in Ohio County, Virginia/West Virginia by 1854
(West Virginia was formed from Virginia in 1863)
GKBopp - 10 March 2006
Bopp

From the below information, it appears that Simon, the immigrant ancestor, came to the U.S. from Baden/Germany and was in Ohio Co., Virginia (now West Virginia), by 1854.

Census Data
Much of the below data is from indices at Ancestry.com as of Feb. 2006 and may contain errors. Check actual census for correct census data (however, remember that census information is often erroneous). There may be additional information in most of the censuses. This family appears in the indices under Bopp, Popp, Bapp, Boggs, Rapp (and once under the surname Simon and first name Bopp) but by looking at the actual documents, it is clear that many of these are clearly typo/indexing errors. Birth years in the indices are approximate.
(In the below "two pages" indicates the entries for the family begin at the bottom of one census page and continue at the top of the next page.)

1870 United States Federal Census > West Virginia > Ohio > Ritchie
Simon Bopp 58? [abt 1812]* Baden  Farmer
Susan Bopp 59 abt 1811 Baden
Henry Bopp 16 abt 1854 Virginia
John Bopp 15 abt 1855 Virginia
Simon Bopp 13 abt 1857 Virginia⁽¹⁾
Valentine Bopp 11 abt 1859 Virginia⁽²⁾
Mary Bopp 9 abt 1861 Virginia
*Indexed as abt 1820 but age on census looks like 58 - probably misread as 50

1900 United States Federal Census > West Virginia > Ohio > Webster > District 129
This may be the same Simon but the birth year is a problem.
Susian Bopp [indexed as such on Ancestry.com as of 12 Feb 06]
Living alone, Dec 1818, age 81, Wd [Widowed], he and parents born Germany.
Immigrated to U.S. in 1854 (in U.S. 46 years)

=================
⁽¹⁾ Simon b. 1857

1880 United States Federal Census > West Virginia > Ohio > Wheeling > District 209
Indexed on Ancestry.com as Suison but it looks like Simon on the actual record and he is probably the Simon listed above in 1870 Census summary.
Suison Bopp 23 abt 1857 VA, Farmer, parents born Germany
Kate Bopp, wife, born Ohio, parents Germany.
No children in household.

1900 United States Federal Census > West Virginia > Ohio > Ritchie > District 106
The census taker interchanged the surname and given name, hence he and family appear under surname Simon (not Bopp) in the Ancestry.com index GKB posted an alternate name on 9 March 2006 under Simon's entry. Children information in census difficult to read.
Simon, Bopp, May 1857, 43 married 22 years, b. WV, parents b. Germany, Dairyman
Kate, Dec 1857, 42 married 22 years, b. WV, parents b. Germany ; 3 children, all living
H-----, 1880 19 b. WV
M----, 1881 18 b. WV
Selma, 1895 5 b. WV

1920 United States Federal Census > West Virginia > Ohio > Ritchie > District 114
Indexed under Simon Bapp (also under Rapp) I submitted a Bopp correction Feb 12 2006
On the census page, it appears the indexer put middle initials before the first name
Simon Bapp 62 abt 1858 WV, parents born Germany, Merchant Store Manager
Catherine Bapp 62 abt 1858 WV, parents born Germany
Halle E Bapp 39 abt 1882 WV (son)
Mame D Bapp 38 abt 1882 WV
Selma F Bapp 25 abt 1895 WV*

This may be Valentine and the Louisa in the below census data:
    Bopp, Valentine [to] Danner, Lucy 04-24-1883

1910 United States Federal Census > West Virginia > Ohio > 4-Wd Wheeling > District 124
Louisa Bopp, Widow, head of household with children.
Louisa abt 1863, WV, Father Germany, Mother Ohio
Louis abt 1884 in WV [ ? at Glass House]
Joseph abt 1890 OH   Apprentice at Glass House
Edmund abt 1892 OH   Apprentice at Glass House
George abt 1901 OH ⁽⁴⁾
Victor abt 1902 WV⁽³⁾
Stephen abt 1905 WV
West Virginia listed as birthplace of children's father.
Based on this, Valentine died between 1905-1910.

1920 United States Federal Census > West Virginia > Ohio > Wheeling Ward 4 > District 85
Louisa Bopp abt 1865 West Virginia Widow, head of household, parents born Germany
Louis Bopp abt 1887 West Virginia
George Bopp W abt 1901 West Virginia ⁽⁴⁾
Victor Bopp abt 1903 West Virginia⁽³⁾
Stephen Bopp abt 1905 West Virginia
(Looks like some of the sons are working for printers)

Victor's grandson reports: Victor Valentine Bopp married Cora Eva Evans and adopted her son and he and Cora had two other sons. (Names were provided but are not included here for privacy reasons.)

1930 United States Federal Census > West Virginia > Calhoun > Sherman > District 6
This does match not wife Cora information and may not be our Victor - unless he had an earlier wife. The census entry is probably Bopp but could look like Boggs to an indexer.
Victor Boggs abt 1900 Head, Glassworker, married age 27
Drew Boggs abt 1906 Wife
Olis H Boggs abt 1929 Son
Dorotha Boggs abt 1930 Daughter
Birth locales for all family members are blank

Have not been able to locate any other Victor in the 1930 index.
