Vector's son, Argyle, may have been interested in Lara-Su in the unaltered timeline judging by how he wished to dance with her at her Unveiling, and Lara seemed to also be interested in him in both timelines judging by how she was happy to dance with him and in the alternate timeline called him her "good friend" and was shown to be quite comfortable being in close contact with him. She also showed a hint of jealousy when Belle D'Coolette began to flirt with him. (SU: #7)

Jacques D'Coolette was also quite charming to her in their first encounter, though it is possible that this is simply the result of his gentlemanly

Locke is a strong parent who cares about his son, but firmly believes that his affiliation with the Brotherhood and Knuckles' duty matters more than his family, or even the possibilty of his son's happiness. This has led him to clash on more than one occasion with Knuckles, and Locke has also had choice words with his ex-wife.

Knecapeon Mace, affectionately known as "Kneecaps the Echidna", is the son of Lara-Le and Wynmacher and half-brother to Knuckles the Echidna. A rather energetic infant, he is extremely attached to his parents and fond of his brother Knuckles, whom he enjoys hitting on the head with a rattle. He was born some time during Knuckles' powerless year in Knothole, his conception having been revealed to Knuckles some time before his temporary death. Kneecaps remained with his parents as they stayed with the Dark Legion as the Angel Island resistance to Doctor Eggman's regime, then in the village built by the survivors of Echidnaopolis, followed by his transportation to the ruins of Albion, which were then rebuilt to serve as a new homeland for the Echidna race (excluding those members of the Dark Legion who were appalled at the loss of their cybernetic implants.)
