Default Combine 3 MySQL queries into one?

I've got three tables, all with different numbers of columns. They all have a column 'cidname' to relate the groups between tables, and 'name' to relate individuals between tables. I'm currently using three "SELECT * FROM tablename WHERE cidname = 'blah'" to get my data, and having to pick out elements from the different result sets. I've been looking at JOIN and UNION stuff, but can't find an example I understand.

Code:
table1
cidname = abcd      cidname = abcd      cidname = dontselectme
name = Goober       name = Noob         name = GMNE
data2 = blah123     data2 = blah321     data2 = 35215

table2
cidname = abcd      cidname = abcd      cidname = dontselectme
name = Goober       name = Noob         name = GMNE
dataa = blahz       dataa = Foo         dataa = 1
datab = blahy       datab = Ret         datab = 2
datac = blahx       datac = Voo         datac = 3

table3
cidname = abcd      cidname = abcd      cidname = dontselectme
name = Goober       name = Noob         name = GMNE
data = foo          data = moo          data = hngo3
Will "SELECT * FROM table1, table2, table3 WHERE cidname = 'abcd'" get me rows
Code:
cidname = abcd, name = Goober, data2 = blah123, dataa = blahz, datab = blahy, datac = blahx, data = foo
cidname = abcd, name = Noob, data2 = blah321, dataa = Foo, datab = Ret, datac = Voo, data = moo
?
