THanks for the help.
I have not been able to connect Gideon Lake to this family.
I think Dean Lake and Eunice Rounds may have had as many as 6 children (based on census records). I have Mary and Elisha and possibly George but that's all. I have a date for the marriage of Dean and Eunice. It was taken from a SAR application by a descendent. Dean's father Noah served in the RI militia during the revolutionary war.
Mary Lake and Lyman Powers ended up in Illinois along with Elisha and his family.
