This HASEMAN GENEALOGY is only a brief outline of our family history and does  not contain details such as information sources, dates for the children in each  family, and other facts for each generation.  These details appear in some 25  looseleaf notebooks and in drawers of surname index cards which are filed in my  home office. These details are the result of some 100 hobby years starting with my mother. I cannot swear that every detail in my outline is correct because  there are sometimes conflicting versions in the records and literature, but I  have tried to display the most logical choice when information conflicts. My  first efforts with the genealogy appear in 5 looseleaf notebooks which I made  in 1990. I then sent copies to my children and some other members of my family.

Surnames were not widely used before 1400.  Before then individuals used just  their given name and one or more discriptive terms referring to: (1) Their father (Fitz Herbert, ap Griffith, verch Griffith, MacCrinan, etc.) (2) Where they lived (de Ruyter, von Aachen, bei der Hase, at church, etc.) (3) Their occupation (baker, miller, smith, knight, merchant, etc) (4) Their title (lord, baron, duke, MP, etc.)
 (5) Their physical appearance (white head, long legs, short, fat, etc) (6) Their character traits (the pious, great, unready, bold, etc) As generations went by, discriptive terms changed to fit the individual, so when surnames were chosen based on discriptive terms often different branches of the  same family were known by different surnames.

Dates may vary for several reasons, especially before 1500.
 1. Birth dates confused with dates of infant baptism (christening). 2. Death dates, with burial date, date of will probate.
 3. Marriage date, with license or contract date.
 4. Conflict between sources: family bible, official records, researched genealogies. 5. Years beginning at vernal equinox (Julian) vs Jan 1 (Gregorian). I converted all    to Jan 1.
 6. Use of different calenders: Hebrew (old testament), Ancient Greek, Ancient Roman,    Julian calender 45BC, Council of Nice 325AD, Gregorian Calender 1582 (accepted    slowly -  Eng & US 1752, Russia 1918, Greece 1923).  
 7. Records citing years from beginning of reign of current King, Emperor, or Pope.
