ELIHU BURRITT'S FATHER'S FAMILY 



Figure 8. The father of the family whose card is shown in Figure 7 is the fifth son, 

 and his identity can be determined, in case of other individuals of the same name, by reference 

 to dates of birth, death and marriage. It was not possible to trace the Burritt line any 

 farther than this, so the third line is blank. Under the column headed "Remarks" are entered 

 various reference marks useful to the worker. One plus sign indicates that the married 

 children had families. Two marks indicate that these families have been carded. S. P. 

 shows that there was no issue.

ELIHU BURRITT'S WIFE'S RECORD APPEARS ONLY ON HER FATHER'S CARD 



Figure 9. To avoid duplication the women are not listed on separate cards, but appear 

 only on the cards of their husbands and fathers — an arrangement that would not meet the 

 approval of the Womans' Party. Thus, in filling out the cards it is necessary to enter the 

 name of the woman's father after her name on her husband's card. 



that in such case there might be 

 found some duphcation, which, how- 

 ever, could be easily corrected by sim- 

 ply discarding the more imperfect du- 

 plicates. In this way the material 

 built up as the life work of one gene- 

 alogist would have a high value to 

 any other person working under the 

 same system. 



How the System Works 



The system can best be ex])lained 

 by illustrations. Standard 5x8-inch 



cards, like those used in many card 

 systems, are ruled as shown in Figure 

 ?. This represents a typical card as 

 filled out. Each card contains the rec- 

 ord of a family group and its title is 

 always determined by the male head of 

 the family, whom we may term the 

 propositus. On the topmost line at 

 the left is printed in clear letters the 

 surname of the family, in this case 

 Burritt, and this is understood as per- 

 taining to all in the column headed 

 "Name." It is especially important
