So my first boy is Cian Michael Miller Gallagher. Miller is his great grandparents last name but we used it for a second middle name. If I name my second boy Jaxon/Jackson Daniel Miller Gallagher, does it sound like Miller Gallagher is two last names ? We rarely ever use the Miller in his name anyway, I just like that it’s in there because my husband was super close to his grandparents. Should we give him his own second middle name so it’s not the same as his brother??
