Another relative has recorded Adam's birth on FamilySearch as Adam Bowie Gibb. How should these events be recorded on familySearch?
Generally, the name in the Details section should be the "Birth Name" which would be derived from the birth certificate. However, if other documentation exists that shows his actual name as something different it would be correct to show that as hit "name". Generally speaking, more information is better than less and more usually helps to more accurately identify a person. HOWEVER, if you would like to make note of these differences, the OTHER INFORMATION section of the Person Page is the place where you would do this. It is important to note all the sources which show these differences. Hope this helps.
