It never ceases to amaze me how many people contact me after doing a Google search for an ancestor or family member.
I used to allow others to download a gedcom file from my website but since I have found my data appearing on other websites and on Ancestry I have disallowed this. I know it is my data because these people have copied holus bolus and even included the sometimes cryptic notes I have attached to people in my tree. So much of the stuff people have copied years ago is now also out of date. I also started to put old family photos on my website but stopped this practice when I found them appearing unsourced on Ancestry. I do not post certificates on the internet as I believe that, in many cases, this breaches copyright.
What I find interesting is that many people think that their trees are 'done' once they have copied some data. If you take some info from my site please firstly verify the sources yourself (some of my stuff isn't well sourced) and please revisit regularly to see if I have added to or amended the records for the persons in whom you have an interest. My site is dynamic, a work in progress, and is continually being updated.
I usually update my site every couple of weeks but, as I have been travelling since late January, only got around to updating it to reflect my last three months of dabbling yesterday. Already this is out of date as last night and today I spent quite some time fixing sources, visiting new indexes on Ancestry, and searching new sources like the digitised newspapers at Singapore's National Library.
