Michaela has also been used sporadically in Poland. The sort of "default" Polish form would be Michalina, but Michaela has been enjoying some little attention for years as well. Last year (2018), 5 girls were given the name Michaela, as opposed to 2692 newborn girls with the name Michalina. Michaela landed on the 434th place, so 30 positions higher that a year before, while Michalina was 24th in the ranking in both 2018 and 2017. It could be nicknamed to Misia, Miśka, Misieńka, Misiunia, Michasia, Michaszka, etc. Possibly Misza, Miszka, Miszunia, Ela, Elka, Elunia, as far as your creativity goes really. A Michaela would most likely celebrate her nameday on 29th September, on the feast day of St. Michael Archangel, though I guess different dates are also possible. It's not an unheard of name over here, but because of the more familiar and fairly trendy nowadays form Michalina, and a bit unusual for the Polish language combination of the sounds "ae", it's considered rare and unique, making it an appealing and universal alternative to Michalina for some parents. Seems to be fairly popular in religious orders though that's perhaps just my own impression.

In the year 1997, there were 9 spellings of this name in the top 1000: Michaela (#100), Makayla (#102), Mikayla (#112), Mikaela (#273), McKayla (#393), Micaela (#463), Mikala (#715), Makala (#851), and Micayla (#952).
I love this name, not only because it's my name, but because I have the amusement of watching people struggle pronouncing my name. They always pronounce it as either 'M-shell-a', 'Michael-a' and actually add in the Michael, or 'Mitch-ay-la'. I don't understand it. It's pronounced 'Me-kay-la'. In the end, it's still funny correcting people who somehow say my name wrong.
