Andrew is believed to have brought his family to Falmouth ME from Londonderry Ireland on the ship "Maccullum" in 1718. It is also believed that Andrew owned two negro slaves.

In 1722, the family held up in their fortified house as the settlement was destroyed by Indians in the Fourth Indian War (Lovewells War). From 8/14/1722 to 1/15/1723 Andrew Sr, Andrew JR, David and Robert were on the muster list of Capt John Gyles of Fort George in Brunswick ME.
