This family seems to be very hard to track. Did Lulu adopt the children out after Nicholas died?

Another family tree at ancestry indicates Raymond's name is Maxfield instead of Maxwell. I assume Lulu married again and her husband may have adopted Raymond? But I don't understand the information about Raymond below, that shows his mother as Margaret Elizabeth Webster. ??? Unless Lulu died and Elijah Maxfield married again???
