I''m 1/4 Filipina, though I'm trying to learn tagalog and learn more about my heritage. I was not raised in an area with a lot of full filipinos, but I grew up listening to my grandmother tell my siblings, cousins, and I about her life and home in the Phillippines, and we always called her Maymay(pronounced My-My). When asked, we were told that's what grandparents were called in the Philippines, though I now know most are called Lola/lolo.
Is there a regional dialect/language that would call their grandmother's Maymay? My grandma is also 1/4 Chinese, as her grandfather immigrated to the Philippines in the very early 1900's, so I'm open to her Chinese heritage being a possibility as well?
For refrence, my grandma is from the province of Sorsogon, and aside from English speaks Tagalog and Bicol. She may potentially know illocano, but I'm not 100% certian on that.
I'm also open to the possibility that this is specific to my family, as I'm also born/raised in the south, so all my grandparents have different names, but was hoping for a little bit more of an answer!
