father Bernard Lippens b 1813 Eekloo - and mother was Marie Louise Flocquin who died 1874
hope it helps 
for what it is worth - it certainly looks like Charles and your gr grandmother had the same parents to me 
thank you for that, the only thing I dont understand from that tree, would be my Maria Valerie Lippens birth Registered at Eeklo on 16th June 1877 by
Karel Francies Lippens, aged 37, born in Oostwinkel and living in Eeklo,
Declared the birth of a child, a female, born at home yesterday at 12 at night,
Born to him and his wife, Rosalie D'hooge, aged 35, born and living in Eeklo,
To whom they have given the name Maria Valerie.
But on the tree that you showed they had another daughter Marie Louise Lippens born 1887? surley they would not have 2 girls named the same?
