When my great grandfather arrived in the US from Wales in 1863, he sought out the Welsh community in Pennsylvania. The young lady he was courting was from Aberystwyth. He joined the Union army to gain her father's approval. Boot camp was held on the train enroute to the front lines. His unit was captured within days and he spent most of the war as a POW. At the end of the war, he returned to Pennsylvania and married my great grandmother. They insisted that their children speak only English. All 19 of them. It's a shame because the number of Welsh speakers in the world is small. All of the children were very successful. Most graduated from college and pursued engineering or farming.
Kudos to you for becoming fluent in English and bringing up your kids with the gift of multiple languages.
San Diego is a beautiful place. Would love to spend some time there, once I retire. (It will be a while) I realize that all Spanish speaking communities are not the same, and I know that So Cal has had more than its share of problems with the Mexican immigrants there. The Mexican community in GA is much different, and similar to the Puerto Rican community where I grew up. The old community is still there, but the kids are completely American.
Sadly, I didn’t realize that Welsh was even a language. I have known several people of Welsh decent, but no one ever told me that they had a unique language. Learn something new everyday.
