Close...but where the devil did you get "mother" from? Mayut is "to have" conjugated to match vashe:
<table border=0>
<tr><td>Ya mayu</td><td>я маю</td></tr>
<tr><td>Tih mayesh</td><td>ти маєш</td></tr>
<tr><td>Vin/vona/vono maye</td><td>вин/вона/воно має</td></tr>
<tr><td>Mih mayemo</td><td>ми маємо</td></tr>
<tr><td>Vih mayete</td><td>ви маєте</td></tr>
<tr><td>Vonih mayut</td><td>вони мають</td></tr>
</table>
(The posessive form of вони being ваше, of course)
And yes, I am aware that that is more Ukrainian than anybody here has any interest in knowing.
добре вечір!
