I am the registered holder of the Tyers one-name study with the Guild of One Name Studies. I hold a wealth of information on the Tyers names and I also have all the English Birth/Death/Marriage references for the Tyers name from 1837 to 2002, together with most of the census references from 1871-1901.
I am more than willing to share whatever information I already hold in regard to your Tyers line(s).
You can check out the Guild of One Name Studies here: http://www.one-name.org
and I also have my own one name study website here: http://www.onenamestudy.org.uk/karen.tyers
My research so far is mainly based in the UK but I am now spreading out to include other parts of the world. If you are a Tyers or are researching the name I would love to hear from you.
