1. What this app is

The Bible names thousands of people, and the family links are scattered across many books. This page gathers them into one tree. It starts with Adam and Eve, then shows their children, then their children's children, one generation at a time as you scroll down.

Each generation has its own colour, and the people in it sit in a grid of three columns so a large family fits on a phone. When you tap a person, the Bible verses that mention them appear on the right.

The tree has three parts, in this order:

1. Traced to Adam and Eve. People whose parents can be followed back, link by link, to the first couple. This is the main tree.
2. Families not traced. The Bible names these families, but the lists do not connect them to Adam and Eve. Each family stands alone, in Bible order.
3. No family recorded. People who are named but have no recorded parents or children, in alphabetical order.

2. How to use it

Turn your phone sideways. The page puts the people on the left and the Bible text on the right, so it needs landscape. A portrait phone shows a reminder to rotate.

• Scroll the left side to go down the generations. More people load as you go, so it stays fast.
• Tap a person to see their name, their father, mother and children as buttons, and the list of verses that mention them. Tap a verse button to read it.
• Listen to a verse. The verse on screen has a small blue ▶ button next to its number, and the highlighted verse button at the top has one too. Tap either and your device's own voice reads that one verse aloud, then stops. While it is reading, the button shows a ■; tap it to stop. Tap a different verse button to change verses, then tap ▶ again. The voice comes from your phone or computer, so it sounds different on each device, and on some phones it pauses when the screen locks.
• Tap a father, mother or child button to jump straight to that person. The arrows beside the name step to the previous or next person.
• Several people with the same name (there are many Josephs and Johns) show a small label under the name, such as "son of Jacob", so you can tell them apart.

The bar at the bottom right

A bar along the bottom of the right-hand pane has three controls:

• Traceable. On shows only the people who can be traced back to Adam and Eve. Off adds the families that cannot be traced and the people with no recorded family. The page remembers your choice on this device.
• Find a person. Type part of a name and tap a result to go to that person. Other spellings work too, so "Timothy" finds Timotheus and "Enosh" finds Enos. If that person is hidden by the Traceable switch, their panel says so.
• About. Opens this page, with the credits and where the data comes from.

3. Resources used

The family data was reshaped into one file for this page, a small number of links were corrected by hand, and a few more were added by reading the verses themselves. Because the data is shared under CC BY-SA 4.0, the family file used here is shared under the same licence.

4. What was corrected

The dataset is still being built, and many of its entries are marked unfinished. Some links were wrong or missing, so these changes were made:

• The line from Adam to Jesus was checked verse by verse. It runs 64 generations, and it follows Matthew's list through Joseph, with Heli noted as the end of Luke's line.
• God was removed as Adam's father, and Luke's extra Cainan was dropped.
• Jacob's sons are ordered by their mothers: Leah, Bilhah, Zilpah, then Rachel.
• About twenty people were added by scanning the verses for phrases such as "begat" and "son of". Those people say "parent link read from" and the verse.
• Several wrong links were removed, such as eight people wrongly listed as sons of one Shimei.

Outside the main line the links have not been checked one by one. A person's panel says "link not yet checked" when that is the case.

5. Good to know

• Not every family is complete. The Bible leaves out many wives, daughters and descendants, so a gap in the tree is often a gap in the text.
• Dates are approximate. Where the dataset has a birth or death year, the person's panel shows it as "about". Treat these as estimates.
• Nations such as Ishmael's or Esau's descendants sometimes appear as people, because the Bible names a nation after its founder.
• Mistake? If you find a wrong link, note the person and the verse so it can be fixed.
