From a researcher examining the Russian State Historic Archive in St. Petersburg, it appears that Klara's surname may have been Stankiewicz and that Wincenty and Klara's manor may have been confiscated in 1836:
"We looked at the documents of two files:
"Fond 384 inventory 15 file 732 (years 1834-1836). Concerning excluding the manor of Bobianski - Lawciszki in the Vilno province from the list of manors subjected to confiscation. 29 pages of documents and versos.
"Fond 384 inventory 1 file 1341 (year 1836). Concerning confiscation the manor of Bobianski, nobleman of the Vilno province.9 pages of documents and versos.
"It turned out that the both files concern one and the same subject. The manor of Wicenti Bobianski had to be confiscated because of his 'absence without leave to the revolt'. This manor Lowciszki (six free serfs) was located in the Rosieny district. The case concerns the lawful of confiscation in connection with the fact that not him but his wife Clara received this manor as the heritage from her father Stanislaw Stankiewicz. The later purchased this estate in the year 1819. In addition, Clara's brothers Josefat and Wicenti are mentioned in the documents.
"So, the Bobianski were registered among the Vilno nobility at last up to the time of revolt."
