They were living at 105 ....Buildings, Fossgate, York. Gustavus was a Tailor, and was born at Towthorpe, in Yorkshire.
He was buried in Grave number 999 at the York Cemetery.
I have a note saying that A Gustavus Wells son of Gustavus Wells died 30th Aug 1869 agd 8 months. This would suggest that the Gustavus born in 1866 also died young. This information was found in the York Cemetery Records.
