Notes:
Andrew Baldwin was born circa 1835 in Ireland².
He bottled mineral water from 1866-1869. The city directories list him with 3 different partners in 4 years¹.

In 1866 he was teamed with John Leitch¹. "Baldwin & Leich" is the name that is embossed on the bottles shown below.
In November of that year, he announced a mutual breakup with Leitch, and that he was going to continue the business without a partner.³

In 1868 he was teamed up with James Flanigan and in 1869 he was teamed up with James Cole¹.
I know of no bottles with "Baldwin & Flanigan" or "Baldwin & Cole" embossed on them, so presumably they re-used the bottles that were embossed with "Baldwin & Leitch".
Baldwin is also listed as a Grocer in 1869, and continues to be listed as a grocer in subsequent years.¹

It appears that after 1869, Cole found a new partner and created Cole & Southey.
