I am searching for any information or living relatives of my grandmother Elice Holik
Elice was born in Prague? 1905 –
Her father was Joseph Holik 1886-1921
Her mother was Franticka Yung
She moved to Sydney Australia with family members when she was a teenager
She married my Grandfather John Major when she was 15 years old and they moved to Wangi Wangi NSW Australia.
Elice and John had 4 children- 3 boys and one girl
Elice died in childbirth in 1927 at Fettercairn, Hamilton , Newcastle NSW Australia
I would appreciate any help that is available
