Dear Mariainne, Thank you, you are incredible. I figured out Louis and Henri were most likely cousins but just couldn't put it together. I don't read Dutch and failed in my translations. This information will be such a delight to my mother who is 85. She has asked many times if I was able to make the connect for her. Because her mother, Rosalie Vosters, daughter of Anna Apol told her to visit the Louve and look at the paintings of her ancestor Louis Apol. Unfortunately, she never made the trip. But, now that we have made the connection, we will be sure to go. I am going to call her now. She will be so excited. I can't thank you enough for your efforts on behalf of me and my family.
