I searched the birth and baptismal records from the Parish of Lipowiec, Ciechanów Land, Mazovian Voivodeship, Polish-Lithuanian Commonwealth from 1718-1747 today and discovered the following entries for the surname Niedziałkowski:
- 01 Jan 1720: Melchior, [birthplace not provided], son of Franciszek and Elena Niedziałkowski (p. 11)
- 12 Oct 1721: Jadwiga, born in Niedziałki, daughter of Mikołaj and Zuzanna Niedziałkowski (p. 22)
- 09 Apr 1724: Wojciech, born in Niedziałki, son of Mikołaj and Zuzanna Niedziałkowski (p.40)
- 30 Nov 1724: Andrzej, born in Niedziałki, son of Bartłomiej and Teresa Niedziałkowski (p. 43)
- 30 Nov 1724: Barbara, born in Niedziałki, daughter of Adam and Katarzyna Niedziałkowski (p. 44)
- 29 Oct 1726: [No name provided], born in Niedziałki, child of Adam and [No name provided] Niedziałkowski (p.55)
- 17 Jan 1703: Antoni, born in [Szyrgały?], illegitimate son of Bibianna Niedziałkowska (p.91)
- 06 Nov 1733: Andrzej, born in Niedziałki, son of Jakub and Aleksandra Niedziałkowski (p. 94)
- 02 Feb 1736: Walenty, [birthplace not provided], son of Jakub and Aleksandra Niedziałkowski (p. 107)
- 20 Nov 1738: Stanisław, born in Niedziałki, son of Jakub and Aleksandra Niedziałkowski (p. 123)
- 24 Aug 1741: Bartłomiej, born in Niedziałki, son of Jakub and Felicjanna Niedziałkowski (p. 139)
- 17 Nov 1743: Marianna, born in Niedziałki, daughter of Jakub and Aleksandra Niedziałkowski (p.152)
- 17 Sep 1746: Chryzostom, born in Niedziałki, son of Jakub and Aleksandra Niedziałkowski (p.170)
In these entries, the dates are presumably the dates of the baptisms, not the births. The maiden surnames of the mothers were not recorded. In the 29 Oct 1726 entry, the name of the child and the child’s mother were not provided . Only one Niedziałkowski birth was illegitimate, that of Antoni, son of Bibianna Niedziałkowska.
Most of these families resided in the village of Niedziałki, the “great nest” of the Niedziałkowski surname. The birthplaces of two of the children were not provided. The birthplace of Antoni, the illegitimate child, appears to be “Szyrgały”, but I cannot find the location of this place, if it was a place at all.
