When did Wiktoria Narutowicz die?

Question

Is it possible to find when Wiktoria ze Szczepkowskich, mother of Gabriel Narutowicz (his Wiki-page) died?

I found rodovid.org but there is no date of death.

I also checked in Gabriel Narutowicz biography by Tadeusz Hołówko but there is nothing about date of death of Wiktoria Narutowicz (Szczepkowska).

Answer 1

Searching online for Wiktoria's married name seems to be drawing surprisingly few results, and all of them blanks. Like "Died after 1865 after age 21 [location unknown]"…

However, she is listed 'properly' at geni.com (and some paywalled sites for the same topic), under her maiden name;
although using 'V' and missing a 't' in her first name, and an 'alternative spelling' for the last name…:

Vicoria Shepovska
Lithuanian: Viktorija Narutavičienė (Ščepauskaitė), Polish: Wiktoria Narutowicz (Szczepowska)
Birthdate: February 23, 1832
Birthplace: Renavas, Mažeikiai District / Telšiai County, Lithuania, Russian Empire
Death: June 01, 1908 (76)
Immediate Family:
Daughter of Ipolit Szczepkowski and Elena Szczepkowska
Wife of Jan Stanislaus Narutovich
Mother of Stanisław Narutowicz h. wł. and Gabriel Narutowicz, Prezydent RP

Note that in other Baltic languages her name would spell 'Viktorija Ščepovskaitė-Narutavičienė' or 'Viktorijas Narutaviča, dzimušas Ščepkovskas' on the respective Wikipedia pages (for Gabriel). Such idiosyncracies need to be accounted for when researching her details further, since for example Gabriel's brother Stanisław Narutowicz did not make much of a career in Poland under that name, but in Lithuania as Stanislovas Narutavičius. This family was rather 'international'…
