I have been researching my family tree for the past 7 / 8 years. I use a number of different websites for my info. I have a worldwide membership to Ancestry.com, full membership to genesreunited and I also have my own backup family tree. I always verify the information that has been entered on other peoples family trees, never take it as gospel. I also use familysearch but again verify the information.
If you are just starting to put your family tree together I can email you a list of questions to ask family members and a couple of standard forms that I use to put all the information down before entering it into the family tree.
A word of warning, don't order BMD certificates from ancestry.com, they charge over GBP20. I have registered with
www.gro.gov.uk for certificates, do your homework first and then enter as much detail as you know. They only charge me GBP9.25 which is the same as if I was living in the UK.
If you are searching family from Scotland, register with
www.scotlandspeople.gov.au they are on a credit system, 30 credits for GBP7 a search is usually 6 credits but you can obtain some of the certificates for the 6 credits you've been charged.
I have over 1200 people in my family tree from all the way around the world and now the next generation are interested in what I have found out, with a bit of luck they will want to carry on the good work.
Happy searching.
