Thanks Debra,
Interestingly, records show Alicia Sands arriving on the Bangalore & her DOB 1838.
I had a relative tell me that rosa Morris arrived also on the ship Bangalore and her death cert shows her birth as 1838. Maybe they are the same person?
I haven't got Rosas marriage cert to Edward, couldn't find it. I think I will get (as u previously suggested), rosa browns marriage cert to Richard underwood. It may lead to more info.
I appreciate your help, cheers chris
