how do i link to this tree

Cornelis Hendrik Loots, g3h1i2,
where exactly do you want to make the connection is YOUR profile Jozua Johannes Georg Loots, b2c6d4e5 already duplicated in the tree of Jan Loots (a) SV/PROG? If so you just have to merge them, or ask a Curator to do so for you. That part of the tree has three Curators and a very active community:

I'll ask one of them to get back to you.

Hi Cornelis (I see you are my 8th cousin once removed)
Welcome aboard

Help me understand what you are asking:

You put Jozua Johannes Georg Loots, b2c6d4e5 on Geni, so I think he is in your tree already.

Are you asking how you link him and your tree into the big world tree?

Hi Cornelis
I sent you the pathway in a message.

Click on my profile. When it opens you will see a big blue "HOW ARE YOU RELATED?' box staring at you. Click on that and Voila!

The site is really fun, isn't it, and there are lots of volunteers who are happy to help you getting going too.

Love Cousin sharon
