"Comparison of this will with the baptisms of the children of Isaac Desborough, the father of the immigrant, allows a number of conclusions. The list of children named in the will matches exactly the list of children baptized to Isaac (omitting those known to have died young). From this we can conclude that the grandchildren named in this will, the children of the testator's deceased son Isaac, are the children of Isaac Desborough, immigrant to New England. Of these six grandchildren, John is called the eldest, and the four granddaughters are consistently named in the same sequence, suggesting that this is the order of their birth."
