THE HOAGLAND FAMILY, OF KENTUCKY. 



In this family nineteen out of twenty-six descendants were deaf, 

 and it is interesting to note that, although one of the members of the 

 family was a hearing person, and married a hearing husband (Reed), 

 their two children and three grandchildren were all deaf. One of the 



descendants, No. l,was

deaf and married a 

 deaf - mute, but their 

 five children all hear. 

 No one could refer to 

 this branch of the fam- 

 ily as a proof that deaf- 

 ness is not hereditary, 

 however. 



The diagram on the 

 following page shows 

 the genealogy of the 

 Fullerton family, of 

 Hebron, New York : 



Fullerton had seven 

 children, all deaf and 

 dumb. There is no fur- 

 ther information about 

 six of these children or 

 their descendants ; but 

 the seventh, Jane Ful- 

 lerton (1), married 

 Sayles Works (2), who 

 was also a deaf-mute, 

 and all their six chil- 

 dren were deaf and 

 dumb. No information 

 was obtained regard- 

 ing the descendants of 

 these six children. 



Those persons who 

 are not familiar with 

 logical reasoning will 

 point to married deaf- 

 mutes with hearing 

 children as proof that 

 such marriages are not 

 to be condemned ; but, 

 in order to prove that 

 deafness is hereditary, it is not necessary to show that all the children 

 of deaf parents are deaf, but only that the number of deaf children,
