1. Year of birth: As seen in the About section, it is claimed at immigration etc as 1876, but there's not a primary source for it and she does not appear in the 1876 birth records for Tokaj. As her place of birth in Tokaj, living with her mother right next door to Celia in Denver and same name as first sons with Celia establish her as Celia's sister, it seems more likely that she was born between 1871 (two years after her brother Jozsef) and the middle of 1874, nine months after her father died). It was a mistake or intentional to be officially younger than she was at immigration, e.g. 13 vs. 16, etc)
2.Her year of immigration as self-reported or by her husband is:
* 1889 in the 1900 Census
* 1892 in the 1910 Census
* 1895 in the 1920 Census
* 1872 or 73 in the 1930 Census, which could make sense if she was born as speculated above, rather than 1876 or 77. But at the time she still had three young children, at least two of whom didn't travel to the USA. So it's not clear what this date represents more than an error.
