Father - Robert Walter Newmark dob 29 August 1923 and born in Brno, Czechoslovakia - lived at 144 Hlinkach until shortly after 15 March 1939 when he, his brother (my uncle Paul), and their mother (my grandmother) left for the UK
Grandfather - Otto Neumark dob 19 December 1888 and also born in Brno. He went to London where he qualified as a barrister, but was called back to Czechoslovakia at the onset of the World War 1 to help with the family textile factory. He then qualified (again) in law in Vienna and gave up his British nationality for Austrian in 1927 to enable him to practice. Several months of increasingly frantic attempts with high level intervention to regain his British nationality finally succeeded (confirmed by correspondence retained at The National Archives, which also indicated their view, confirmed by the German authorities, that he was Austrian), with the British nationality papers arriving at the house (144 Hlinkach) on the day of the invasion (15 March 1939). Although the Gestapo arrived to arrest him that day, they turned back on sight of the papers (this last from my father's memories only, I don't know how to confirm this). The National Archives also record "detention" (?does this mean internment as a foreign national?) in Vienna after 1939 and perhaps into 1941, before he was sent to Zurich. However, I don't know where, and if this indeed could be counted as "main residence". But if not, why not?!
I don't have his birth certificate, only his marriage (15 November 1922) and death certificates (25 February 1947).
I have actually taken no steps to date to obtain further documents. This is because on application six months ago the Austrian government advised that all necessary research would be undertaken by them and about 40 researchers were employed specifically for this task. However, I think that their caseload is very high and my strong circumstantial evidence, but lack of documents, may well make my case more difficult than many.
