Click on the link for a PDF copy of the Słownik Geograficzny Entry for Piertanie. The entry, translated from the Polish, states:
Piertanie, a village on the small lakes Pierty and Wigry, Suwalki Powiat [District], Hutta Gmina [municipality], Wigry parish. Twelve viersts [1 vierst = 1.0668 km] not far from Suwalki, it has 15 homes, 109 inhabitants, 327 mórgs [1 mórg in the Russian Partition = 1.388 acres] in territory. Swampy land. In 1827 there were 7 homes, 38 inhabitants.
The parish for Piertanie is in Wigry. The Family History Library in Salt Lake City has church records for Wigry from 1808-1882. I may be able to find some relevant records in these microfilms.
I’ve mentioned the Słownik Geograficzny several times in the past. I use this reference often to discover to which parish a particular village belonged and to learn more about the village. Some entries, like the entry for Piertanie, are very brief. The entry for Wigry, the parish, is much more extensive.
