Thank you for your reply Maria. The names are correct as they appear on a tomb-stone in Patagonia. And they also more or less tie up with the family I found in Aberdare.....the names, the dates (alsmost exactly) location ie Tresalem which isn't that big an area and child's name and dob. Thanks for the details of the Mimosa journey in 1865. Haven't seen that one before. However, they traveled at a later date which was 1874 aboard the Hipparcus which is why the appear on the 1871 Census but I can't find any of them in 1881. I've looked up Elizabeth Williams to see if she appears on the Births register and unfortunately, there are several of the same year. I suppose I need to find out the exact quarter she was born along with their registration district which I would think would either be Pontypridd or Merthyr Tydfil.....probably the latter. Am I going along the correct lines of investigation or am I missing something which would help me along?
