The topic for this week is ‘SLOW’.
Last week I interpreted ‘Fast’ in terms of generations, so this week I’m interpreting ‘Slow’ similarly.
Great Grandfather Alexander Johnston was born in 1829.
His son my Grandfather Alexander Johnston was born in 1868 when his father was 39.
My Father Warwick was born in 1912 when his father was 44.
I was born in 1940 and my daughter was born in 1977.
So that is 142 years (1829 to 1977) and four generations.
If one generation normally takes 25 years then one would expect my daughter to be 6th generation.
No wonder many of my DNA matches are difficult to identify as they are with people two generations younger than me!

I think that I can go better in the slow generations. My grandfather, Arthur Henry, married when he was 45 and my mother, who was his last child, was born when he was 70. This means that, if I can survive until 2036 (which is a bit unlikely), then 3 generations will have spanned 200 years. Perhaps brother Arthur has a better chance, as he is 10 years younger than i am.

I should have considered your line of the Hunt family when I wrote about them in Week 25 (“Fast”) – so both Fast and Slow in what is essentially one large family.
