Hugo,
yes i learned that one a wee while ago, need things confrimed so easy to guess an get it wrong !!!
thus patience is a virtue, you just keep an eye open for the clue to pop up and follow it through.
i started as a kid, i have a little book that i drew a family tree on as a 12yr old, sitting in front of the fire at tan y bryn farm waunfawr. i only took it as far as my great grandparents, and i asked questions but i didnt make notes in those days. so i have been hunting up these hughes and southworths for a good few years. i have patience, and even if it has to wait till the next set of census records published in a few years time

hopefully something will spring up before then!
_))*i guess if i could just find their marriage, then i could get the certificate and parental names, as nothing turns up for robert in Llangefni. (does it have any other names? that come under llangefni, i presume if he said Llangefni it meant that.
but i was chatting to my mum on the phone earlier, and told her the story of robert and the policeman, and she came out with, that emma/ishmael had a relative who was a policeman in caernarvon; on questioning she couldnt remember anything. maybe it was that one he ruffed up.
and she also told me that it was ishmaels brother, that would have signed the burial papers for him in new york and that they had to send to his wife emma for the money to bury him, so i might try to find which brother that was !!! as seem to have come to a halt for the moment on robert.
me mum has hughes's as well from Llanberis way, and they are as equally elusive.
ive sent an email to the st helens archives re that will you linked to (after googling and getting that it was the sale of baron hill to robert from the estate of mr Evans esq.) to see if they by any chance have any more details on Robert other than the bit i found, in their archives and if a transcript is available, if there is. see that pen y buarth was also sold (thats where robert and ann lived prior to baron hill. as renters i would guess).
Would anyone know the maiden surname, of John Owen of avalon (the aldemans) first wife margaret?
so summarising wonder if baron hill was sold between 1911 and 14 or passed onto a family member.
where/what happened to robert and Anne in those years
info on their children, where they went or married to whom. giz a job i can do that!!!
