Stephanie,

Unfortunately we have no details of any family call Blackwood-Sewell in the UK. Looking through articles on our website I can see that in March 2000 we had an enquiry about Blackwood-Sewell's from Miles in Australia who says that his family traced their family up to the arrival in New Zealand but nothing beyond that. It is therefore likely Frank is of this family that originates from NZ but its a mystery as to where the joined name came from. Perhaps there was a marriage on the boat and thus the Sewell & Blackwood families were joined.
