Nice post mate.
A DNA kit arrived today from ancestry.com for me so that is a massive coincidence, I am going to send the saliva kit back and see what comes from it and maybe start looking up the tree.
I was estranged from my Mum, and not a huge fan of the majority of her family, they were all from Limerick, mentioned on here before that we were due to meet up again and potentially reconcile after a long time apart a week after she died, lots of unanswered questions from her side but not sure I want to know, the stories she told me when I was young about children's homes and abuse were pretty bad, pretty sure she only has a half sister left now in Milton Keynes.
My Dads side was different, would have loved to know them more but most died before I was born (He was 55 when he had me) He died 9 years ago now and I regret so much not asking him more questions near the end but I didnt know he was going to die , he had a pretty colourful past from the stories I did listen to as a kid, he arrived in Liverpool from Belfast during the war as a 16/17 year old pulling bodies off boats he once told me, he ended up in County London as they used to call it by the time I came along and I grew up between Brentford with my Mum during the week and Uxbridge with him at weekends.
I am sure I have loads of family in the Belfast/Crumlin area from his side but all his siblings died by the time I was 12, I did find his Dads grave last time I was back there to scatter his ashes.
Will be interested in how you get on.
