Hi Marilyn, I know of Bethel House as Dr Thomas Fiaschi married there in 1876. I have seen it mentioned quite a few times in regards to marriages during the 1880s. You could probably locate some more information in a history of the Congregational Church or the Presbyterian Church. There is a book in the Local Studies Collection at Hawkesbury Library called "Congregationalism in Australia" by G. Lindsay Lockley shelved at RL285.8 CON. The Sands Directory might also identify a street number. (I would check it for you but I am not at work today) Cheers Michelle Nichols
