I started when the 1901 Census became available on line, when I looked up my grandparents on both sides to see where they were living. My family are great ones for telling tales, so I knew a bit about the family.
Having discovered, to my amazement, that one grandmother was living with plenty of siblings and her parents in a tiny house very close to a part of London we had, without realising, visited regularly, I was intrigued to go further.
Then my cousin, who had been entrusted with documents relating to family history, as the eldest son of the eldest son of the family, somewhat reluctantly passed on the information to me. He only had a daughter and therefore couldn't maintain his proud position as senior in the family.
Imagine his distress when I subsequently discovered that, contrary to his understanding that he was the eldest son of the eldest son of the eldest son - our mutual greatx3 grandfather was illegitimate, and our mutual greatx2 grandfather WASN'T the eldest son, but the third!

I don't think he's quite recovered, but I have an extensive tree, just in the 19th Century, of all the relatives.
