I have managed to discover that my Spanish DNA goes back to the Palaeolithic and Magdelenian period which is about 19,000 years ago! I discovered this on a fantastic free dna site called mitoYDNA. You just upload your DNA and have access to all your haplogroups and everything is carbon dated as they compare your SNPs with archeological finds.I ended up with many from The Basque Country, Cantabria, Catalonia, Andalusia, Burgos, Madrid and a few more regions including the Guanches from 1000 years ago in the Canary Islands,. My mother has some Lebanese DNA from the Crusaders and they ended up conquering Al Andalous in the 800s and probably mixed with the locals, My father is Irish and also has a lot of Spanish DNA , especially from the Basque regions and a few more from all over Spain,
I have also compared these findings on My Heritage which is fantastic if you have the premium subscription as they tell you where your ancestors came from starting in 1600 up to the year 2000. They also break them down into regions, surnames and Christian names by centuries. They also have an interactive timeline from 1600 to 2000 which shows you with a world map where your ancestors immigrated to over 400 years.
I have also confirmed my findings on a few other sites such as Gedmatch.com and Yourdnaportal which although not as detailed as they 2 above , just confirm your Spanish roots. I also found a few famous Spanish Conquistadores on my materenal side who went to the New World in the 1500s and funnily enough my mother also has some South American indiginous DNA especially from Boliva, Colombia, Puerto Rico, Mexico and Peru, I have managed to discover the names of the tribes with the help of Gedmatch.com and myliving Dna. This is just my Spanish DNA but I also have about 30 other ethnticities I have to investigate. I wouldnt like to say how many hours I have dedicated to this but it must be hundreds if not thousands.
Funnily enough I decided to leave England in 87 and come to live and work in Madrid and my other sister moved to Tenerife 5 years ago. Maybe our Spanish ancestors were calling us??
