I found the certificates on some on Ancestry.com and some on other sites. Most of them just list the child's name, age, date of death or the day of the record of death. Place of death, and maybe a cause of death. None of these children appear on census.A few I found I could connect with William or Carl/Charles Kerls.I am assuming most of them were from these two families or sons of the same family. I did find that Wm. and Carl Kerls both had burial plots in the Old Bethlehem Cemetery and their records noted that an infant son in wm. plot, Lena was noted as infant daughter of carl but buried in wm Kerls' plot. Not much else can be documented. Most children did not die at hospital but at homes or place was noted as a neighborhood or just a street.So I have been trying to use the census for the streets and addresses but these people kept moving up and down the street between the census years. Thanks for all your replies.
