My name is Harriet Hellberg living in Sweden and my grandmother had an cousin by name Gustaf Henrik Hvass, born 22 april 1862 in Näs Ånimskog Älvsborg county in Sweden,he was Wholesaler and Disponent and he would be living in Australia according to a will from 1926 on his brother Thorbjorn Hvass.
I know of a source that Gustaf Henrik Hvass was wanted for forgery and therefore escaped overseas.
He was married(22 april 1892) to Julia Hagman born 27 june 1865 in Hässjö Västernorrlands län. I have no clue when he he went abroad, but maybe about 1893 and forward somewhat. He could possible have been in Kapstaden South Africa at the first place from an assumption of the source I have, and in his brother's will, from 1926, he would have lived somewhere in Australia. I attach 2 file, I hope you can use google translate to get a hint. My best/ Harriet Hellberg
