Hi Jo,
Welcome to the forums, i hope you find them useful in your online social marketing quest.
My father and I have dealt with this type of business in great detail, he has traced our family tree back several generations. Very, very interesting as he was also adopted so he has both, an adopted family tree and a biological family tree.
Look forward to your input on the forums, if you have any queries or questions just fire away. We're all very nice on here
Kind Regards
Neil Gould
