Delete with foreign keys

I have three tables --
   CREATE TABLE name (id INT PRIMARY KEY, str VARCHAR(20));   CREATE TABLE place (id INT PRIMARY KEY, name_id INT
REFERENCESname(id));   CREATE TABLE data (id INT PRIMARY KEY, place_id INT REFERENCES place(id));
 

I want to delete all place and data rows which reference specific
names, but not the names themselves.  I can do it like this:
   DELETE FROM data d WHERE exists (SELECT id from place p WHERE d.place_id = p.id AND p.name_id IN (SELECT id FROM
nameWHERE str LIKE 'Fredonia%'));
 
   DELETE FROM place WHERE name_id IN (SELECT id FROM name WHERE str LIKE 'Fredonia%');

but it seems rather roundabout, and I wonder whether the EXISTS and IN
business is slow.  Is there some way to do it using JOINs?  I think of
something like this:
   DELETE FROM place p, name n WHERE p.name_id = n.id AND n.str LIKE 'Fredonia%';

but I don't want to delete the name rows.  Then I think of this:
   DELETE FROM place p WHERE p.name_id = name.id AND name.str LIKE 'Fredonia%';

but I feel uneasy about the two separate name references when the
table is not named in the FROM clause.  Maybe that's just my novicity.

I also wonder about getting fancy and ending up with SQL specific to a
database; I don't have any plans to migrate, but I try to avoid
branding my SQL.
