ABRAHAM BEAMISH WERRIBEE/WYNDHAM VICTORIA

Trying to piece together my Beamish tree and seem to be confused as to which of the 3 Abrahams, 3 Margarets and 3 Anastasia Beamish's buried in the Werribee Cemetery belong to my line! Our ancestor, Catherine Jane Beamish was b. 1877 Wyndham to Francis Thomas Beamish and Elizabeth Young Kingston.As they were married in 1865, I assume my Francis' parents were Abraham and Margaret(Kingston) Beamish as I have an extract for Francis Thomas b 1840 to this couple.The other Francis Thomas was born 1865 to Abraham and Anastasia (Beamish) Beamish. Our Francis was born Co. Cork.Was this the Abraham and Margaret with 7 children who arrived on the "Fanny" in 1852?Can anyone please verify this and tell me a bit about the family.Who was the other Francis Thomas Beamish? I don't seem to understand the Lahana line on the GinniSwanton website!
