While every house in Slovenia has a civic address, many houses also carry a household name. These names are how other people typically referred to that family. This house carries the name of Grdunkini. The origin of the name is related to the original patriarch of this house, Johan Pavlakovič from Grduni. Even though this house was inhabited by a Pavlakovič family, that surname only lasted for one generation before it was changed to Kajin. This is the second house which is an offshoot from the Gornji Kajinovi.
The oldest record we have found to date for a person from this house is for Johan Pavlakovič (Mikičev from Grduni) b. 1849. He married Barbara Ostronič (Golek pri Vinici 7) b. 1854. Together they had 7 children, including:
1A. Barbara Pavlakovič b. 1876, m. 1898 to Jurij Kajin (Gornji Kajinov).
1B. Ana Pavlakovič b. 1879. At this time, it is unknown what happened to her afterwards.
1C. Johan Pavlakovič b. 1881, m. 1905 to Marija Mravinec (Maljevacova from Perudina) — they remained at this house.
1D. Marija Pavlakovič b. 1884, m. 1904 to Johan Flajnik (Ziljanov from Hrast).
1E. Jože Pavlakovič b. 1886, m. 1908 to Johana Gorše (Mišičeva from Hrast).
1F. Katarina Pavlakovič b. 1888, m. 1910 to Johan Rogina (Golek pri Vinici 12).
1G. Johana Pavlakovič b. 1893, died at the age of 76. At this time, it is unknown if she was ever married or had children.
Johan Pavlakovič [1C] and his wife Marija Mravinec had 1 child:
2A. Marija Pavlakovič b. 1906, m. 1930 to Franc Kobetič (Kovačov from Drežnik).
At this point, the Pavlakovič lineage ends at this house. Jurij Kajin (Gornji Kajinov) (son of Jurij Kajin and Barbara Pavlakovič [1A]) lived here with his wife Ana Balkovec (Maradinova from Zilje).
Jurij Kajin and his wife Ana Balkovec had 2 children.
