Hi Tyke.
I don't know if I can help but I can tell you what I know.
My Great grand father Henry Long, or his dad by the same name, began Longs Transport in Bradford. During WW2 this was bought by the government. After the war my grandad, Harold Long, and his cousins bought the company back.
My grand father was in the RAF during WW2, posted in either Africa or India. When he returned he married Shelia (who worked in Yeadon).
Henry Longs Transport was sold over 30 years ago. I know this because I'm now 26 and I can't ever remember him owning it.
Harold had 2 children, a boy (now aged about 57) and a girl (now aged 51). The boy had two children, a girl who's now 30 and a boy who's 27. The girl had two daughters, me and my sister who's 23.
My mum and uncle are both married. My Gran and granddad died around 20 years ago.. My Gran from elderly illnesses and my granddad from a heart attack.
I hope this has been of use to you,
RAF wife.
