I found a page for this name and found to way to request a correction so I will repost the comment I left about it here.
"
Xandinho" is not an actual name. "-inho" and "-inha" are diminutive suffixes in Portuguese that can be used for any male or female name, respectively, and such diminutive forms are seldom (if ever) used as actual names. The short form of "
Alexandre" that is used as a name is "Xande" (pronounced SHAN-də).
