The first
Jesuits in the locality were based in
Clare from 1848. They were being urged by Catholic
Prussians at
Tanunda, who felt uncomfortable among the more numerous
Lutheran Prussians, to establish a Catholic settlement in the Clare district and so began a search for a suitable locality. Section 91 in the
Hundred of Clare had been purchased in 1850 as a speculation by
Thomas Burr, former Deputy Surveyor General of South Australia. Jesuit priest Aloysius Kranewitter was delighted with the prospects of the hilly and fertile location and, through his influence, Burr surveyed this land into allotments for leasing, which became the township of Sevenhill. In December 1850, in consultation with Burr, the allotment layout and limits of the new settlement were settled by Kranewitter. By January 1851 Kranewitter was calling the future site
Sevenhill Township. The first lots became available from April 1851, all for 31 years' lease with easy right of purchase terms, and soon many Catholics, particularly Irish, Polish, and German, were moving there from Kapunda, Tanunda, Burra and other districts. Over time, particularly during the 1930s and 1940s, it became unclear whether the correct name of the township was Sevenhill, or Sevenhill
s, arousing debate. Clare philatelist
Albert Fryar provided conclusive evidence (cuttings from envelopes and postal cancellations) that the original title was indeed Sevenhill. ==Saint Aloysius Church, seminary and college==
