What's the connection between the Hilton and Lithuanians?

South Australian Lithuanian Antanas Lapsys, Architect was " part of the consortium which developed the Hilton Hotel on Victoria Square; a project which was unprecedented for South Australia in terms of its size and as its status as the first ‘international’ hotel in Adelaide". (http://www.architectsdatabase.unisa.edu.au).

Well known Hilton chef, Cheong Liew first moved from Malaysia to Melbourne in 1969 to study electrical engineering, but instead became a chef. In 1995 he opened The Grange restaurant at the Hilton one of Adelaide's most successful restaurants. Cheong is married to Lithuanian Ziukelis, and has trained several of the family as chefs.

Do you know of any more connections?
