There are probably many saints named Lynne but the Catholic Church has not canonized any of them yet. Remember saints are people in heaven or on their way to heaven. All Christians dead and alive are saints. The Catholic Church justs selects some of the most extraordinary examples, does in-depth research, and canonizes them. "By canonizing some of the faithful, i.e., by solemnly proclaiming that they practiced heroic virtue and lived in fidelity to God's grace, the Church recognizes the power of the Spirit of holiness within her and sustains the hope of believers by proposing the saints to them as models and intercessors."
