Hi John,
There is a Family Tree on Ancestry with following details;
Ephraim Robson, born 13/11/1785 Morpeth, died 26/8/1824 Leith,Midlothian,Scotland.
Parents -John Robson and Mary Thompson
Spouse- Mary Ann Ingram
Their son John Robson, born 1822 died 1891 Cundletown.N.S.W. Australia
Have to go to bed now, can send message to tree holder in morning ( 2.00 a.m. in Sydney now) or maybe someone in England can do it for you now.
I also have a Robson from Morpeth in my tree, there seem to be a lot of them some born Scotland.
Lots of luck,
Trish
