Tracing this story we become informed also about the marriages of Petschacher’s daughters. Agathe Peschacher married Gyula Elischer, who was a well-known physician, professor of radiology. Maria Lujza Petschacher ’s husband was Ede Szenes, who was the heir of one of the most exclusive groceryand delicatessen shops in the Inner City. When he tried to put the affairs of his life in order in 1915 - presumably because of joining to the army - he pledged himself in a notarial deed to pay 25.000 Kr. annuities to Maria in case of cessation of their marriage for any reason. [HU BFL -VI 1.192 - 1915 - 1283] [http://archives.hu ngaricana. hu/en/lear/666751/?query=HU%20BFL%20-%20VI 1,192%20- %201915%20-%201283] Marta Etelka Petschacher lived with her husband Henrik Szalay, a merchant, in Vienna. We know from a notarial deed, that their adress was VIII. Lerchenfelderstrasse 8, Wien in 1920. [BFL_VIl_217_a_1920_2433] The fourth daughter, Olga married Worthington Estelle Hagerman, a painter and musician from Indiana, USA, and she became a painter herself. Numerous traces of the life of these families can be detected in the database. We meet three of the daughters last time in a notarial deed of 1937 when Agatha and Maria were already widows. The Petschachers’ tenement 27. József körút is a potential starting point for lots of other research directions using Hungaricana. The digitised address registers, which are accessible in pdf. format in the Library section and searchable by full-text, offer the possibility to reconstruct the list of tenants and the annual changes through querying „József körút 27 ”. Being tenants’ listofthe register organized by the names of the tenants, to compile a list of a particular house, mainly following the changes year by year, this work couldn’t have been done with reasonable allocation or without digitisation. We are fortunate enough in this case to have the opportunity to piece it out with a list in the Orphans’ Office file, which was compiled at the beginning of the guardianship over Irma Wen inger and contains even the rental fee of each flat. Conducting new querys on the names of the tenents we get valuable hits about most of them in different archival and printed sources, opening new and new lines of networks of these people. Following these lines in a consistant way, the researcher can reconstruct the networks of society in which the inhabitants of a house (or a neighbourhood, a larger bloc...) were embedded. József körút 27 could make a boast of some renowned tenants around the turn of the century, who merit our interest for themselves. We find here the excellent historian Dávid Angyal (1857-1943) as an employee of the University Library, who became latéra professor of modern history. Jenő Péterfy art critic and literary historian, an outstanding figure of the aesthetic discourse of the era moved to an otherflatfrom here supposedly not much before his suicide committed in November 1899. Emil Demjanovich, a well-known physician was the personal doctor of Mór Jókai and Kálmán Mikszáth, the most famous Hungarian writers of the 19th century.
