Thanks Brian. I tend to think that the first-hand reporting of Horatio's birth location would be more reliable, esp if it's been consistently reported during his lifetime (Age 27, NY; Age 37, NY; Age 46, NY; Age 57 NY). But, since we don't have his actual birth records yet, he could have actually been born in Ohio.
I see there were several Collins families who moved from New York to both Michigan and Ohio during that same time period. Apparently word got out that there was good farmland in those areas.
