Hi Belinda,
I am researching hannabus family too ( my mother is a hannabus) and have come to a standstill with regards to this lady.
Are you sure it is Ethiopia? my family do not know where he went/where she was from, Africa or the Islands off Australia have been mentioned...
I am the daughter of Beryl, who's father was Sidney Hannabus - I have seen a photo of John Hannabus ( Sidneys father - my g.grandfather), and he was very dark coloured - I am wondering if this lady was his mother?
I would be grateful for any info', also if I can help in any way...
Sara.
