COVID-19 Update

In the wake of Covid-19 difficulties in hosting a live event, we are currently restructuring FHDU 2021 for a virtual event.

Sadly, the ongoing COVID-19 saga has caught up with FHDU 2021. We have reluctantly decided to change our in-person event into a fully virtual online event instead. We were all looking forward to a real, live, in-person event. Unfortunately, that is not to be.

But this gives us the opportunity to significantly re-format FHDU 2021. We are looking at this as a positive opportunity. We can now bring a significantly more valuable event to people around the globe.

This webinar introduces what it is and how you can do it, along with a summary of what it can and cannot help you achieve. Some examples using the DNA Painter website are included alongside suggestions for other tools and software that might help you with your DNA research goals.
