Hi Erin, Sounds to me like your Andrew died if Lucy was called a "widow" and she may have had their last child near his time of death or something and that is why you see the child with her in the 1920 census with the last name of MOODY. If you found that she had remarried somewhere then apparently your Andrew died between the 1910 and 1920 census'. Again, if you found Lucy called a "widow" somewhere thats a pretty indication that Andrew had died. Hope this is your family. Take care.
