thanks for your email. There's been an enormous amt of work done on all lines of the Niblett family by Mike Niblett who is a Brit living in Canada. I met him last month in Toronto.
I will foward your email to him and give you his email address.
He will be more than happy to hear from you. I think your Nibletts might be the lot who settled in NSW and they'be proved to be elusiveso any info Mike and I can get from you will mean he might be able to help you - or me, but more him. I come from the Kent/Sussex Nibletts who moved to Victoria.
My email address is firstname.lastname@example.org if you would like to contact me directly.
If you google Mike Niblett you will get onto his mound of work, including that done by Ray Niblett, a Brit, living for the time being in W.A. - south of Perth.
Looking foward to hearing from you. I collect photos or our relatives and if there are any links I'll be more than happy to share them with you. It's suprising what you learn through photos.
