RECORD OF FAMILY FACULTIES. 



3. Suppose one or more of his own children are married and have 

 families ; -then he may select one or other of his sets of grandchildren, 

 as the " Children " of the pedigree, and work upwards from them. 



4. Suppose the writer to be female ; — then similar conditions to 

 those in i, 2, and 3, will be applicable, with obvious modifications. 



It will be noticed that I have assigned a descriptive number to 

 each ancestor ; these will be found convenient for reference, and less 

 confusinsf than the cumbrous verbiagre of " Father's Mother's Father," 

 and the like. The principle on which the numbers have been given is 

 such, that they have useful and interesting properties, and that the method 

 admits of indefinite extension.^ If we except No. i, which means 

 " a child," without distinction of sex, every even number refers to a 

 male, and every odd number to a female ; thus 2 is the father, 3 is the 

 mother. Again, if we double the descriptive number of any person, 

 we obtain that of his father, which by the addition of i becomes that 

 of his mother ; thus, the father and mother of 2 are respectively 4 and 

 5, those of 5 are 10 and 11. Every number contains, for those who 

 care to analyse it, a complete history of the place in the genealogical 

 tree of the ancestor to whom it belongs. 



DESCRIPTION OF THE TABLES. 



The Tables begin with an Index to Ancestors, which explains itself. 

 As the record progresses and the Index is simultaneously filled up, the 

 eye will dwell upon the gaps that remain, and the writer will feel himself 

 stimulated to obtain the deficient information, The next fifteen tables are 

 separately headed and numbered in accordance with the diagram. Blank 

 pages may be interleaved by the writer in them whenever he requires 

 additional space, or wishes to introduce photographs which add much 

 to the interest and value of family records. A blank page is interposed 

 between the Table of the Father and that of the Mother, as more space 

 is sure to be required for their records than can be found in the printed 

 forms. 



Page I is for a list of the Children in the Order of their Birth, and 

 is intended to serve much the same purpose as the blank pages in a family
