Seeking ancestors from Holland
I am seeking information regarding the following, all born in Holland:
John (Jan) Melpolder
Alida Mand (Melpolder)(Actually a foundling, hence the name Mand.)
Dirk Jan DeBruin-b. 1837-possibly Amsterdam
Berendina Krozenbrink (DeBruin)-b.1838
Henry DeBruin
All were born in Holland and emigrated to USA prior to 1900.Naturally, any information will be greatly appreciated.
