New York, U.S., Arriving Passenger and Crew Lists (including Castle Garden and Ellis Island), 1820-1957

Validator (claude-opus-5-5, 2026-10-28): consistent, confidence 1/4, tier record.
Lines 28–29 list Frantisek Konecny, 18, glazier, and Jan Konecny, 46, joiner, both from Kostany/Hostany, Bohemia; Jan's nearest relative is wife Veronika Konecny, Kostany 166. The manifest cannot state a birth date or place, and the age matches 1867 only if the voyage was in 1913; the header year is unclear and could be 1906. The Bohemian residence, rather than Štítná nad Vláří in Moravia, is a real reason to doubt this is the same Jan Konečný. The link to the claimed birth needs other evidence, such as a later record naming wife Veronika or son František together with Štítná.
Matches: Line 29: given name 'Jan', family name carried by ditto from line 28 'Konecny' (Konečný); Age 46, which gives a birth year of about 1867 only if the sailing year is 1913; Nationality Austria, race 'Bohemian', which fits an emigrant from the Czech lands
Flags: Last permanent residence is given as Kostany (or Hostany), Bohemia, not Štítná nad Vláří, Moravia; the nearest relative is wife Veronika Konecny, Kostany 166, which points to a Bohemian family rather than a Moravian one; The sailing year in the header (Bremen, May ...) is hard to read; if it is 1906, age 46 implies birth about 1860, seven years before the claimed 1867
Limits: A passenger manifest gives an age, not a birth date or birthplace; No house number or birthplace is recorded, so house 131 cannot be checked here; The sailing year on the header is partly illegible
