In the polar coordinate system, the ray $l: \theta = \frac{\pi}{6}$ intersects the circle $C: \rho = 2$ at point $A$, and the equation of the ellipse $\Gamma$ is $\rho^2 = \frac{3}{1+2\sin^2\theta}$. A Cartesian coordinate system $xOy$ is established with the pole as the origin and the polar axis as the positive half-axis of $x$.

(Ⅰ) Find the Cartesian coordinates of point $A$ and the parametric equation of the ellipse $\Gamma$;  
(Ⅱ) If $E$ is the lower vertex of the ellipse $\Gamma$, and $F$ is any point on the ellipse $\Gamma$, find the range of values for $\overrightarrow{AE} \cdot \overrightarrow{AF}$.
