A Simple System of Designating Relationship 



211 



To make the ancestral numbers, in 

 all cases, indicate abstract relation- 

 ship, consider them as powers of 2, 

 plus whatever figure is required to 

 complete the ancestral number. 



2. The father =2+0 



3. The mother =2 + 1 



4. The father's father =4+0 



5. The father's mother =4+1 



6. The mother's father =4 + 2 



7. The mother's mother =4 + 3 



8. The father's father's father =8+0 

 15. The mother's mother's mother 



= 8 + 7 

 etc. 

 "Mother" = 2 + 1 

 The mother of 2 = 2X2 + 1=5 

 The mother of 3 = 3X2 + 1 = 7 

 The mother of 9 = 9X2 + 1 = 19 



"Maternal Grandfather" =4 + 2 

 Maternal grandfather of 



2 = 2X4 + 2 = 10 

 Maternal grandfather of 



3 = 3X4 + 2 = 14 



Maternal grandfather of 



9 = 9X4 + 2 = 38 



"Paternal grandmother" =4 + 1 

 Paternal grandmother of 

 2=2X4+1=9 

 Paternal grandmother of 

 7 = 7X4+1=29 



Paternal grandmother of 

 15 = 15X4 + 1=61 



These tables indicate some of the 

 curious properties that these ancestral 

 numbers possess. By their use we can 

 indicate complicated relationships in 



John Hubbard 

 m. Mabel Russell 



Daniel Hubbard 

 m. Martha Coit 



William Hubbard 

 m. Joanna Perkins 



Samuel Hubbard 



m. Mary Anne Greene 



Gardiner Greene Hubbard 

 m. Gertrude McCurdy 



an exact manner, and in a way that 

 cannot be expressed in words. 



The system of ancestral numbers is 

 admirably adapted for the discovery 

 and study of consanguineous marriages 

 as was found in my study of the ances- 

 try of Mabel Gardiner Hubbard. 

 (Beinn Bhreagh Recorder, Vol. XV.) 

 It was observed that the same individ- 

 ual may have two or more ancestral 

 numbers. For example: John Hub- 

 bard, who married Mabel Russel, 

 appears as No. 32 and also as No. 

 88, indicating that two of his descen- 

 dants have married one another. This 

 means that Mabel Gardiner Hubbard 

 traces up to John Hubbard by two 

 lines. 



In order to discover the consanguin- 

 eous marriage, divide both ancestral 

 numbers by 2 until you reach the 

 husband and wife: — 



Nos. 4 and 5 are husband and wife, 

 and they are both descended from 

 John Hubbard, (who married Mabel 

 Russell), and the connecting numbers 

 indicate the two threads of ancestry 

 and the sex of the intervening ances- 

 tors. By hunting up the numbers in 

 the list of ancestors given in the Recor- 

 der, Vol. XV, pp. 3-36, we can ascer- 

 tain the names of the individuals 

 concerned. Nos. 32 and 88 represent 

 the same individual, John Hubbard. 

 Represent him by a single circle: — 



Daniel Hubbard 

 m. Mary Greene 



Elizabeth Hubbard 

 m. Gardiner Greene 



Mary Anne Greene 

 m. Samuel Hubbard
