Yes, fascinating to see where you've come from and back to 1650 is good going. Same with me, one side is well documented, but father's is a dead end. Le Farrar does sound Norman or thereabouts.
I made a guess earlier. without actually checking how far back it went - it actually goes back as far as 1550 and in one thread there is a tenuous link to Sir John Winter, the 15th century Royalist. I should not have looked at it, because I then spent much of yesterday evening on it, digging away for more fascinating details. I managed to find out that my grandparents had got married in the main church of the local city and the engine driver great uncle had got himself buried in the local minster. I had originally assumed they were quite poor, but those two facts suggests they were quite a 'well to do' family.
When I had originally began the 'digging', around eight years ago, I began it with nothing more than vague memories of who might have been relatives. One possible family of relatives had emigrated to Australia back in the 1950's, with there two young sons. I then managed to make contact with one of the sons about four years ago and we were able to confirm we were cousins. He said his mother, then a widow, had moved back to the UK back in the 1980's and coincidently had moved to the very same village I moved to into in the late 1970's and still live. Which suggests our paths must have crossed very many times in the local high street
I had begun it, just knowing the names of my two parents. They were each the youngest in their families and I came along late in parents lives, so most of my relatives had passed away when I was quite young. Both of them had then passed away too, long before I gained any interest in tracing my roots. As a youngster, every adult was called uncle or aunt, irrespective of any actual relationship, which made it incredibly hard work to sort the wheat from the chaff.
One uncle I remembered as having some sort of mental issues and remembered when visiting him, being told not to make any sudden noises. I managed to trace that to shell shock resulting from WW I. Another, I remembered visiting us in his RN uniform, some years after WWII. My dad, I was told was on minesweepers during WWII.
All fascinating stuff and a bit of research pulls at least some of the memories together, to make sense.
