From a fly leaf of a book (no indication of how old the book was):
"Andrew Davison children by his wife Elizabeth.
1 - Emelia Davison, born Nov. 9, 1749.
2 - Mary Davison, born July 20, 1752.
3 - Joseph Davison, born July 9, 1754.
4 - John Davison, born October 19, 1757.
5 & 6 - Hannah and Sarah Davison, born Feb. 14, 1764.
7 - Josiah Davison, born October 4, 1767."
'A well established fact is there was another son, Andrew, born 1746, whose line is well known.'
