I was able to create a view from some of the data in my MySQL database, as shown below:
mysql> CREATE VIEW phonelist AS
-> SELECT parent.parentID AS ParentID,
-> ParentPerson.firstName AS ParentFirstName,
-> ParentPerson.lastName AS ParentLastName,
-> ChildPerson.firstName AS PlayerFirstName,
-> ChildPerson.lastName AS PlayerLastName,
-> GuardianHomePhone.homeNumber AS GuardianHomePhone
-> FROM parent
-> JOIN player ON (parent.parentID IN (player.motherID, player.fatherID))
-> JOIN person AS ParentPerson ON (ParentPerson.personID = parent.parentID)
-> JOIN person AS ChildPerson ON (ChildPerson.personID = player.playerID)
-> JOIN addressDetails AS GuardianHomePhone ON (GuardianHomePhone.personID = parent.parentID);
Query OK, 0 rows affected (0.00 sec)
mysql> select * from phonelist;
+----------+-----------------+----------------+-----------------+----------------+-------------------+
| ParentID | ParentFirstName | ParentLastName | PlayerFirstName | PlayerLastName | GuardianHomePhone |
+----------+-----------------+----------------+-----------------+----------------+-------------------+
| 8 | Gregory | Peck | Michael | Peck | 034871234 |
| 9 | Laura | Peck | Michael | Peck | 034871234 |
| 10 | Martha | Petersen | Matt | Petersen | 034724321 |
| 10 | Martha | Petersen | Christopher | Petersen | 034724321 |
| 11 | Chris | Michaels | Richard | Michaels | 034791212 |
| 11 | Chris | Michaels | Shaun | Michaels | 034791212 |
| 12 | Nadine | Michaels | Richard | Michaels | 034791212 |
| 12 | Nadine | Michaels | Shaun | Michaels | 034791212 |
| 13 | Barry | Dackers | Harry | Dackers | 034871996 |
| 14 | Kevin | Mitchell | Daniel | Mitchell | 034742886 |
| 15 | Rebecca | Mitchell | Daniel | Mitchell | 034742886 |
+----------+-----------------+----------------+-----------------+----------------+-------------------+
11 rows in set (0.00 sec)

Creating this view was a problem, but it is described below that I have problems with navigation:
I also need to add a team in which each player is in this view. Since getting a team name to match requires joining four tables, I am having problems joining things together. I managed to create a separate request that matches the players teams below:
mysql> select person.firstName, person.lastName, team.teamName
-> from person join player on person.personID = player.playerID
-> join teamAllocation on person.personID = teamAllocation.playerID
-> join team on teamAllocation.teamID = team.teamID;
+-------------+----------+------------+
| firstName | lastName | teamName |
+-------------+----------+------------+
| Michael | Peck | U10 Red |
| Christopher | Petersen | U10 Red |
| Richard | Michaels | U11 Orange |
| Shaun | Michaels | U9 Yellow |
| Matt | Petersen | U11 Orange |
| Harry | Dackers | U9 Yellow |
| Daniel | Mitchell | U9 Yellow |
+-------------+----------+------------+
7 rows in set (0.00 sec)
mysql>
The result that I visualize in my head looks something like this:
+----------+-----------------+----------------+-----------------+----------------+----------------+-------------------+
| ParentID | ParentFirstName | ParentLastName | PlayerFirstName | TeamName | PlayerLastName | GuardianHomePhone |
+----------+-----------------+----------------+-----------------+----------------+----------------+-------------------+
| 8 | Gregory | Peck | Michael | U10 Red | Peck | 034871234 |
| 9 | Laura | Peck | Michael | U10 Red | Peck | 034871234 |
| 10 | Martha | Petersen | Matt | U11 Orange | Petersen | 034724321 |
| 10 | Martha | Petersen | Christopher | U10 Red | Petersen | 034724321 |
| 11 | Chris | Michaels | Richard | U11 Orange | Michaels | 034791212 |
| 11 | Chris | Michaels | Shaun | U9 Yellow | Michaels | 034791212 |
| 12 | Nadine | Michaels | Richard | U11 Orange | Michaels | 034791212 |
| 12 | Nadine | Michaels | Shaun | U9 Yellow | Michaels | 034791212 |
| 13 | Barry | Dackers | Harry | U9 Yellow | Dackers | 034871996 |
| 14 | Kevin | Mitchell | Daniel | U9 Yellow | Mitchell | 034742886 |
| 15 | Rebecca | Mitchell | Daniel | U9 Yellow | Mitchell | 034742886 |
