I am looking for any information on John Younker (of NY) and Catherine Maher (of WI). They lived in Summit SD in 1895 thru 1897 at least. They had two daughters that were born there - Agnes (b: 1895) and Catherine Alice (B; Mar 1897, my grandmother). I have been told that John died in Summit shortly after Catherine Alice was born but I have no proof. If anyone can find anything on this family during this period, I'd really appreciate it.
