Sorry for slow response time. I'd love a copy of the obit. If you like, I'll send you my mailing address (I live in Hong Kong) along with all of the info I have on Jacques Oliveira. I didn't make print-outs of what I found but working from my notes I produced at least a couple of pages on his activities from arriving in the US in 1859 until 1867. He was, incidentally, touring England with Tom Thumb just before going to the US. There are, however, some big gaps in what I know. I have little form 1862 to 1865. I believe he was in New Orleans during this time, but haven't any details or proof.
In any case, I'll try to get what I have to you in a day or two.
