Sorry, I thought you said you had no connection to this Manton family.
As far as I am aware no other relatives of this family immigrated to Australia.
My John is buried in Adelong. He had three siblings, Selina, my G Grandmother, also buried Adelong & Elizabeth who were born in Kidderminster England and Alfred who was born on route to Australia and his birth is registered in Melbourne. This family grew up in Gundagai NSW.
