Ancestor List for Jan de Klerk ahnenlist
The ancestor list uses the "ahnen" numbering system and presents seven generations in plain text. There are no images or colors. This makes it well-suited for printing when you're doing offline research.

Compact Family Tree
This alternative tree view is packed with eight generations — up to 254 ancestors — along with birth and death dates and locations. The downside is that it's not a conventional tree format; it may take a couple minutes to orient yourself.

Descendants descendants
Since Jan has no children the descendants page isn't available. Do you know of children? Please let the profile managers know.

DNA Ancestors and DNA Descendants DNA view
Genetic genealogy is the new frontier. Our two DNA views are designed to help you use genetic testing to confirm and expand Jan's genealogy. The DNA Ancestors page shows the specific ancestors from whom Jan gets his Y chromosome and mitochondrial DNA. Especially helpful for some serious genetic genealogists is the inheritance pattern for Jan's X chromosome, also shown here. The DNA Descendants link isn't active because Jan has no children. It may still be possible to test connections to Jan by testing other descendants of his ancestors who inherited the same Y chromosome, X chromosome or mitochondrial DNA.

DNA Ancestor Confirmation Aid check mark
This tool helps you take things a step beyond the DNA Ancestors and DNA Descendants views. The ambitious goal: scientific confirmation of each parent-child relationship in Jan's tree. This is still fairly complex but it's getting simpler every day.

Dynamic Tree
The dynamic tree expands to include an unlimited number of generations of parents and children. You can zoom in or out and pan around for the perfect view as you browse.

Family Group Sheet family group sheet
This simple page illustrates nuclear families based on marriages. It's handy when someone had children from more than one marriage. It may not be useful here unless you add children.

Family List
This flexible tool enables you to see more ancestors and/or descendants on one page than anywhere else on WikiTree.

Global Family Tree Connection
How many degrees of separation are between Jan and Henry VIII? This Connection Finder includes relationships through marriage, so it is not a genealogical cousin calculator like our Relationship Finder, but it's a fun way to illustrate how closely we're all connected.

Index of de Klerks
This page shows all the de Klerks on WikiTree. It's useful for genealogists with an interest in the surname that goes beyond Jan. There are a variety of connected tools, such as de Klerk DNA Connections and DEKLERK G2G.

Printer-Friendly Tree printable tree
This view parallels the pedigree chart above but it is optimized for printing. It can be used as a fill-in-the-blanks form at a family gathering.

Profile of Jan
The profile page is the central place for organizing and viewing information and sources on an individual. This tree & tools page is a supplement to it. Whenever you see Jan's name on WikiTree (and ideally, elsewhere on the Internet!) it will be linked to the profile at where De_Klerk-460 is Jan's unique WikiTree ID.

Relationship Finder Find Relationship
Enter De_Klerk-460 and any other WikiTree ID to find the genealogical relationship between Jan and the other person. It will name the relationship, e.g. "third cousin twice removed," and show the trail of connections to a common ancestor. Although not everyone on WikiTree shares common ancestors, finding and connecting them is our ultimate goal. See the Relationship Finder Quick Links to check for relationships to US presidents, Mayflower passengers, Magna Carta Sureties and more.

Research with RootsSearch
Automatically search for Jan on more than 20 different genealogy websites with the RootsSearch app.

Share Tree on Facebook shareable tree
Download and share an attractive family tree image. This is a great way to elicit information and photo sharing from family and old friends. You might be surprised at who replies. The "Wikid Shareable Tree" is another option. You can just copy and paste the URL into your favorite social network.

Surnames surnames
The surnames page is a quick reference sheet that displays seven generations of Jan's family names. Many members share its URL via e-mail, e.g. with a DNA match to ask if the other person recognizes a surname.
