Joseph’s parents were Jacob Foutz Sr. (1800-1848) and Margaret Mann (1801-1896). Jacob Foutz was wounded in the Haun’s Mill Massacre in October 1838, and was the captain of the Second Fifty of the Second Hundred of the LDS settlement of Utah in spring of 1847. There is an article about them on a web site compiled by one of the descendants of Joseph’s older sister Susan Foutz Brown (1823-1842). While the article is captioned “Susan Foutz Brown”, it is really more about her parents, and hence Joseph’s parents.

Many of the census records for Joseph’s children report their father’s place of birth as Pennsylvania. His own census records, though, report him as born in Missouri, and Mormon migration annals show that his parents moved from Pennsylvania to Hauns Mill, Missouri in 1836. He may have been conceived in Pennsylvania, though. :-)

1850 census of Utah Co., Utah territory, records on p. 32 as family #234:
Margaret Foutz, widow, 48, b. Penn; Joseph, 13, b. Missouri; Margaret D., 11, b. Illinois; Jacob, 6, b. Illinois; Caroline M., 3, b. Deseret, Utah.

Her death certificate records Caroline Amanda Foutz, age 77 years 11 months 2 days, born 6 Mar 1839 in Ohio, died 8 Feb 1917 in Richfield, Sevier Co., Utah, widowed, father Esbon Child, born in USA, mother’s maiden name Mary Haskin, born in Ohio, cause of death unknown except observation from inability of stomach to handle or digest food, informant Mrs. Delilah Oranders, Richfield, Ut, burial in Richfield Cemetery.

Her obituary in the Richfield Reaper of 17 Feb 1917 reported:

FUNERAL SERVICES HELD SUNDAY FOR PIONEER LADY

Services over the remains of Amanda Foutz were held in the Second ward chapel Sunday afternoon there being quite an outpouring of relatives and friends to pay honor to the memory of the dead woman. The speakers were Judge H. N. Hayes and W. H. Seegmiller, each of whom spoke in praise of the quiet life of the deceased and of her many virtues. The music was by the ward choir and a quartet of voices. The floral tributes were many, of chaste design and particularly appropriate for the occasion. The interment was in the city cemetery.

1860 census of Utah Co., Utah territory, Battle Creek precinct, Pleasant Grove P.O., enumerated 25 Sep, lists on p. 371 as family #3227/2515:
Jos’h F., Fouts, 23, farmer, b. Missouri; Amanda, 21, b. Ohio; Jos’h, 2, b. Utah.

(What I’ve indicated as “Jos’h” is Jos followed by a superscripted h.)

1870 census of Utah Co., Utah territory, Pleasant Grove precinct, Pleasant Grove P.O., enumerated 23 Aug, lists on pp. 10-11 as family #75/74:
Foutz, Joseph, 33, laborer, b. Missouri; Amanda, 31, b. Ohio; Joseph, 12; Caroline, 10; Alonzo, 7; Mary, 3. All children born in Utah. Emma, 17, b. Ohio.

Emma is Joseph’s second wife.

1880 census of Yavapai Co., Arizona, Mowery Abbey, enumerated 5 June, lists on p. 1 as family #1:
Foutz, Joseph L., 42, b. Missouri Penn Penn, farmer; Amanda, 41, wife, b. Ohio Ohio NY; Emma E., 27, wife, b. Iowa Missouri Missouri; Caroline E., 19, dau; Alonza E., 17, son; Mary D., 12, dau; Emma E., 10, dau; Margaret, 9, dau; Nora A., 8, dau; Cora C., 7, dau; Ida M., 6, dau; Junius L., 4, son; Maude, 5/12, b. Jan, dau. All children born in Utah.

Of the parent birthplace fields, Mary D’s is reported as father born in Iowa and mother in Missouri. This is somewhat odd, even assuming a reversal of parent positions, in that she is a daughter of Amanda, born in Ohio. All the other children report their father as born in Missouri. The mother’s place of birth is reported as Ohio for Caroline, Alonzo, Emma, Nora, Ida, and Junius, and as Iowa for Margaret, Cora, and Maude. This does not match the LDS sealing records, according to which Emma, Nora, Ida, Junius and Maud are Emma’s; the other’s are Amanda’s.

The following household is headed by Joseph L. Foutz Jr, age 22, oldest son of Joseph and Amanda.
