Hello again Foxglove
Dorothy's trip in 1956 was a visit back to the UK. My parents were living at 131 so she must have used that addres for the return voyage. I was born there.
Dorothy was questioned at length by my maternal grandmother (so family history goes) and my natural grandfather's surname was apparently Bishop. It was a very small place then, we only found one Bishop in the census whose age would fit - he was the son of the landlord of a pub in Tenterden and Dorothy's grandfather Tom was landlord of the pub in nearby Rolvenden, so it might fit. I'll never know though because he was killed in WWII. (The pub in Rolvenden is called The Star, still going and a very nice little pub.)
There is a quite grand tombstone in Rolvenden churchyard commemorating Tom and his family. Looking further back, the family seems to have been farm labourers in Rolvenden.
The name Judge is not very common - I did read somewhere that there is an Irish branch and there could well be some travellers who had to leave Ireland in the 19th century, but I found nothing in my family tree.
I tried once to see if I could find my relatives in New Zealand as I've lost track of all my relatives on that side of the family, but couldn't work out how (any advice gratefully received).
