This particular carte de visite is marked with the subject's name and dates: "Jacob Sedlacek, 7/25/1851 to 4/14/1915. I found a Jacob Sedlacek who fits in the 1910 US Federal Census for Richland, Sarpy, Nebraska: Jacob, 54, immig. 1866, b. Austria, with his wife Mary, 49 and children: Anton, 25; Bessie, 22; James, 20; John, 13; Katie, 11; Emilia, 8 & Anna, 6. [Daughter, Bessie, married a Mr. Elseman. She died 27 Dec 1960 in Bellingham, Washington. Source: Washington Death Certificates, 1907-1960]
The Sedlacek family also appears in the 1900 census for Richland. Jacob's birth month & year is listed: Jul 1849. There are two additional children in this census: Frank, b. July 1881 and Joseph, born March 1883.
In Douglas County Nebraska Marriage 1854-1881 I found "Jacob Sedlacek, [29, Omaha, born Bohemia, father: John Sedlacek, mother: Mary Milarik (Milnarik)] married Mary Pivonka [19, Omaha, b. Bohemia father: James Pivonka, mother: Anna Kolar.] Marriage date: 6 March 1880."
Find-a-Grave provides a picture of Jacob's final resting place. His gravestone reads, b. 25 Jul 1850, d. 11 Apr. 1916. While these dates do not match the photo's exactly, I'm not too concerned. The dates differ throughout most of the records I've looked at. The person who wrote this down on the photo could have been operating from memory. I notice they are a year off on both dates, but have the correct months.
