Seeking info on my 2nd ggrandparents - Hendrik BOUMANS (1842-1917)  m: Ludovica Joanna DASSEN (1840-1912) - Antwerp, BE.  

what exactly would you like to know? you already seem to have the birth and death year of your 2^nd greatgrandparents, with that you can look up who your 3rd greatgrandparents are in the BMD-records for Antwerp that are available online at FamilySearch [here (there are annual and decennial tables to assist you)].

e.g. here's the birth record of Ludovica Joanna Dassen, born 24.12.1840, daughter of Petrus Henricus Dassen, carpenter, age 32, Walefeuchten in Prussia and of his spouse Maria Therisia Geeraerts, age 28, born in Antwerp

Thanks Peter B.!!!!   I was so excited when I found this forum!  You gave me another line!  I was looking for their parents and I should have stated that.  I would love to find family connected to my family!  It's so hard when you don't know the language!  My mother was from Antwerp and she spoke Flemish, French, English and some German. I live in the US.  Thanks again!
