Kekulé family tree
operation
Between the Q button for source display and the date information at the top of the index card window is the field for the ancestor number according to Kekulé. Right-click in this field and a window will open providing you with menu items for ancestor numbering. Click Remove existing numbering to remove a previously created Kekulé numbering system, or Create Kekulé numbering system to create a new one. Once complete, statistics are displayed showing the number of assigned Kekulé numbers and the number of ancestors; the difference is a measure of ancestor attrition due to multiple ancestors.
Double and multiple ancestors
Multiple ancestors are numbered multiple times. In this case, a downward-pointing triangular arrow appears in the Kekulé number field. Clicking and holding the left mouse button scrolls down the complete list of ancestor numbers. You can limit the number of different ancestor numbers per person in the Omega settings . Numbering starts from 1
The numbering begins with the current record card and proceeds upwards in the pedigree chart. The subject receives the number #1 . If the numbering started with the subject's number 1 , then the subject's siblings – if any – are distinguished by 1a to 1z . Different numbering
However, you can also assign any other number to it. This is useful if you want to exchange data with other researchers: suppose your ancestor with the number 780 is the ancestor with the ancestor number 1288 of your research colleague. Then, after deleting the existing numbering, you can start a new numbering sequence from your ancestor number 780 , but beginning with number 1288. All analyses will then display the ancestor numbers as they apply to your research colleague. After the analyses and data exchange are complete, you can have the ancestor numbering sequence recreated starting with your own ancestor number 1 .
restrictions
The Kekulé numbering always reflects the state of research/data entry at the time it was created. If you find and enter parents of your earliest ancestors, they will only receive ancestor numbers when you initiate a new numbering process. A maximum of 31 consecutive generations can be numbered.
Miscellaneous
Ancestor numbers are marked with a preceding # symbol in references to persons .
