Terminology Detail: Explanation of numbering:
Each person listed on a tree has been given an identification.
For example the first member of the Horton tree, William Horton, has been given a letter [h] but left unnumbered.
The next generation is numbered as follows: [h.1] for Henry, son of William.
The twelve children of son Henry are identified by [h.1.1] to [h.1.12]. Therefore Sarah, the first child of Henry is [h.1.1] whereas Richard, the seventh child is [h.1.7].
The next generation is identified by three numbers: e.g. [h.1.7.1] for Sarah, the first child of Richard.
This is how it works: John Denys Horton (me) is [h.220.127.116.11.2.2], which identifies that I am the second child of Denys [h.18.104.22.168.2], the second child of Denys snr [h.22.214.171.124], the first child of Richard [h.1.7.3], the third child of Richard snr [h.1.7], the seventh child of Henry [h.1], the child of William [h].
