Format of family trees

Note that there are separate record numberings for births, banns, marriages, and deaths.
(A bann is a declaration of the intent to marry.)

a person is described in one line, with the given name first and the surname in ALL CAPS
an "x" before a name indicates a male,
an "o" before a name indicates a female
births and deaths are expressed as
```
       Date1 Year1 #Akt1 - Date2 Year2 #Akt2
```
- not all of these items are necessarily present
- Date1 (Date2) refers to the date of birth (death)
- Year1 (Year2) refers to the year of birth (death)
- Akt1 (Akt2) refers to the record, or Akt, number
  in the archival birth (death) records of that year
- in some instances, an event was recorded in a later year,
  in which case that fact will be shown in parentheses.
  For example: Mar 15, 1834 (1836 #75)
  means that the birth on Mar 15, 1834 was recorded as birth Akt 75 of the year 1836
a person's spouse is shown in the following line,
an "m:" preceding the name indicates a wife,
an "M:" preceding the name indicates a husband
the children of a (married) couple are shown, in chronological order when dates are known,
under the lines of the (married) couple with a common indentation
a person's second spouse (presumably after death or divorce of the first spouse)
is shown after the lines of the descendents of the first spouse
the indentations are synchronized by use of vertical lines that alternate using the | and ! symbols
an absence of one of the vertical lines indicates that a relationship (usually of the groom-bride, but sometimes of the child to the parents) is probable but uncertain
