You can find her birth certificate on FamilySearch:
https://familysearch.org/pal:/MM9.3.1/TH-1-13889-50876-46?cc=1831469&wc=10768119.
You have found her birth date in Genlias, so you have also found the names of her parents, Hendrikus van den Heuvel and Petronella Gevers.
Petronella died on 07-08-1890 in Veghel, a few days after Catharina's first birthday. I did not find a second marriage of her father, I think he did not get married again. Maybe you can find something in his death certificate: Hendrikus van den Heuvel died 24-07-1939 in Veghel.
Catharina gets married with Antonius Wilhelmus van Lieshout on 18-11-1907 in Veghel.
You should take a look in the "bevolkingsregister" of Veghel to see where and with whom she lived during childhood. An index of those registers can be found online, you can order a copy of those pages.
All info mentioned can be found searching the database on BHIC. Certificates can easily be found on FamilySearch through
www.genver.nl, browse to Noord-Brabant and then Veghel.
Birth = geboorte
Marriage = huwelijk
Death = overlijden
Don't forget to look in the "huwelijkse bijlagen", the papers the couple had to show when they applied for a marriage licence.
