I have just come across your 2008 post asking about Ebenezer & Sarah Holland.
For the past 42 years we have owned the house that they built in 1895 in the Adelaide suburb of St Peters, South Australia.
Both died while living in the home, Ebenezer in 1933 & Sarah in 1934. Their Daughter Ida retained ownership until 1949.
They bought the land on which the house is built in 1885, and are listed in a directory in 1884 & perhaps 1883.
I have a considerable amount of other information should it be of interest. My direct email address is email@example.com
