When I was at primary school we were given a project, a family tree, I was laughed at & felt humiliated in front of a whole class being told this was impossible (paternal line)!!! ...

You decide whether it's possible/impossible?
Annie (with all the certs.) 
I can imagine you you felt. Here's mine, if it is any consolation:
me, 1948
mother, 1914
grandfather, 1874
gr-grandfather, 1821
And my brother is considerably younger than I am.
As to the question of the thread, which ties in to the diagram. It didn't hurt my interest in family history that my mother made her children
memorize the Irish townlands of her parents. Or that, on rainy days, she would suggest we get out our gr-gr grandparents family Bible (on my father's side) and see if we could 'figure out who those people are.'
But what got me going was an email from my sister saying "did you know we are related to Clark Gable?" [as in the American actor, Gone with the Wind, etc.] Well we aren't, but I did find my ancestors in Ireland and I now know who 'those people were' in the family Bible.
edited to add: and my father was considerably older than my mother
