Hello

I am looking for help in trying to locate a burial:
Elisabeth Kempen (Born Verheijen as her mother was not married to my Great Grandfather at that time) was born in Helden on the 23 March 1894, she married Martinus Lemmen on the 22nd of February 1915 in Maasbree and had a child, Karel Henricus Lemmen in May of that year.
Elisabeth died on Tuesday 17th June 1919 at the age of 25, seven months before her son, and is probably buried in the parish of St. Lambertus in Helden, does anyone know if any records exist online for the parish, I am trying to find out if a grave is still in existence or not, up until I started doing my mothers side of the family no one knew she even existed, in fact it was a member of Rootschat who found me the marriage record of my Great Grandparents and the note of the "Adoption" of Elisabeth to my Great Grandfather.
Any help or tips on how to proceed would be very welcome and greatfully received.
My very best regards always.
Frank.
