My name is Jacqueline Ticehurst and I am an 'Australian Ticehurst'; although currently living in Paris with my husband as expats for 3 years.
My father is Geoffery Ticehurst and his father is Patrick Ticehurst from Forbes in NSW.
When I was younger I remember going to Ticehurst reunions in Forbes. There would be many many Ticehursts at these reunions.
My Aunty (June Ticehurst) has, I think, put together a family history. Perhaps this would help you out.
I don't recall meeting a Francis Ticehurst but I was quite young when I used to get dragged along (as I thought at the time) to these familty reunions. However my grandparents are a wealth of information on matters concerning the Ticehurst familty. I have been told by them that all Ticehursts are related as it is just one family.
Anyway let me know if perhaps I can be of assistance.
By the way are you the Gary Ticehurst who is a helicopter pilot? When I was working in Sydney ( I worked with the media a bit) I was often asked if I knew Gary Ticehurst.
