Hi Lee and Mylissa:
Sorry it took so long to get back to you.
Since I didn't receive too many response to my inquiry, I sort of dropped this research.
So far, all I know about the Fukushima clan of Kumamoto Prefecture is that they were pretty well-to-do farmers and were samurais.
My grandfather, Heijiro, I believe was a Nishimura but was adopted by the Fukushima clan because the clan didn't have a male heir to carry the Fukushima name. I was told that this was the custom there under these circumstances.
My great-grandfather's name was Heikuro Fukushima.
I hope this information is of use to you.
If it is, we might kin.
Te
