Diane, I might be to late for this look up but, Winfield S. BROWN and his wife, Elizabeth BROWN lived in Manhattan in 1910. Their oldest children at that time are Grace (age 20) and Robert (age 18). John S. DONNELLY and his wife, Julia DONNELLY lived in Manhattan in 1900. Their oldest children at that time are John S (age 18) and Edward (age 16). If you have the time I would very much appreciate your help. Thank you. Yvonne
