Since posting this message, I've uncovered more accurate info on my greatx3 grandfather - William Beckman. He was born in 1820 in either Belgium or Holland and came to the US in 1840. I believe he had a daughter named Esther with his first wife. He married Mary(maiden name unknown)in 1857 and settled in Plymouth, Mass. They had 4 boys- Albert, Charles, Harrison, and William. I'm looking for where in Belgium he came from, other family here or there, and more info on his wives and children?
