Question: Do the Trailing bellflower and the Pseudocydonia sinensis belong to the same plant family?

full_context: Document 1: Campanula poscharskyana: Campanula poscharskyana (Serbian bellflower, trailing bellflower) is a semi-evergreen trailing perennial, valued for its lavender-blue star-shaped flowers, native to the Dinaric Alps in former Yugoslavia.
Document 2: Pseudocydonia: Pseudocydonia sinensis, the Chinese quince, is a deciduous or semi-evergreen tree in the family Rosaceae, native to eastern Asia in China, and the sole species in the genus Pseudocydonia. It is closely related to the east Asian genus "Chaenomeles", and is sometimes placed in "Chaenomeles" as "C. sinensis", but notable differences are the lack of thorns, and that the flowers are produced singly, not in clusters. The Chinese quince is also closely related to the European Quince genus "Cydonia"; notable differences include the serrated leaves, and lack of fuzz.
Document 3: Trailing bellflower: Trailing bellflower is a common name for several ornamental plants in the bellflower family and may refer to:
Document 4: Tree peony: Tree peony is the vernacular name for the section "Moutan" of the plant genus "Paeonia", or one of the species or cultivars belonging to this section. It consists of shrubs that have perennial aereal woody stems. Other peonies do not have perennial woody stems, but their stems die back after the growing season, to emerge again from buds just below the surface early in the following year. Tree peonies have been in culture in China for millennia, and it is likely that hybrids came into being in gardens, where different wild tree peony species were planted closely together. They are used in China both for medicine and as an ornamental, particularly the hybrids called "Paeonia suffruticosa". These hybrids in particular, but other tree peonies too are called 牡丹 (mu dan) in China.
Document 5: Paulownia: Paulownia is a genus of six to 17 species (depending on taxonomic authority) of flowering plants in the family Paulowniaceae, related to and sometimes included in the Scrophulariaceae. They are present in much of China, south to northern Laos and Vietnam and are long cultivated elsewhere in eastern Asia, notably in Japan and Korea. They are deciduous trees 12 – tall, with large, heart-shaped leaves 15–40 cm across, arranged in opposite pairs on the stem. The flowers are produced in early spring on panicles 10–30 cm long, with a tubular purple corolla resembling a foxglove flower. The fruit is a dry capsule, containing thousands of minute seeds.
Document 6: Campanula spicata: Campanula spicata, common name the spiked bellflower, is a herbaceous biennial or perennial plant of the genus "Campanula" belonging to the family Campanulaceae.
Document 7: Chaenomeles: Chaenomeles is a genus of three species of deciduous spiny shrubs, usually 1–3 m tall, in the family Rosaceae. They are native to Japan, Korea, China, Bhutan, and Burma. (Burmese: ချဉ်စော်ကား ) These plants are related to the quince ("Cydonia oblonga") and the Chinese quince ("Pseudocydonia sinensis"), differing in the serrated leaves that lack fuzz, and in the flowers, borne in clusters, having deciduous sepals and styles that are connate at the base.
Document 8: Campanula rapunculoides: Campanula rapunculoides, known by the common names creeping bellflower, or rampion bellflower, is a perennial herbaceous plant of the genus "Campanula", belonging to the family Campanulaceae.
Document 9: Phellodendron: Phellodendron, or cork-tree, is a genus of deciduous trees in the family Rutaceae, native to east and northeast Asia. It has leathery, pinnate leaves and yellow, clumped flowers. The name refers to the thick and corky bark of some (but not all) species in the genus.
Document 10: Quince: The quince ( ; "Cydonia oblonga") is the sole member of the genus Cydonia in the family Rosaceae (which also contains apples and pears, among other fruits). It is a small deciduous tree that bears a pome fruit, similar in appearance to a pear, and bright golden-yellow when mature. Throughout history the cooked fruit has been used as food, but the tree is also grown for its attractive pale pink blossoms and other ornamental qualities.
Document 11: Campanula: Campanula is one of several genera in the family Campanulaceae with the common name bellflower. It takes both its common and its scientific name from its bell-shaped flowers—"campanula" is Latin for "little bell".
Document 12: Exochorda: Exochorda is a small genus of flowering plants in the family Rosaceae, native to China and central Asia (Turkestan). They are used as ornamental plants with the common name pearl bush, or pearlbush. Numerous species have been described on the basis of differing appearance and geographical separation, but a systematic study revealed that the different types are closely related and probably all descended from a single species that formerly had a wide distribution that has been fragmented by habitat loss. As a single species the correct name is "E. racemosa".
Document 13: Chaenomeles: Chaenomeles is a genus of three species of deciduous spiny shrubs, usually 1–3 m tall, in the family Rosaceae. They are native to Japan, Korea, China, Bhutan, and Burma. (Burmese: ချဉ်စော်ကား ) These plants are related to the quince ("Cydonia oblonga") and the Chinese quince ("Pseudocydonia sinensis"), differing in the serrated leaves that lack fuzz, and in the flowers, borne in clusters, having deciduous sepals and styles that are connate at the base.
Document 14: Mertensia ciliata: Mertensia ciliata is a species of flowering plant in the borage family known by the common names tall fringed bluebells, mountain bluebells, and streamside bluebells.
Document 15: Mertensia longiflora: Mertensia longiflora is a species of flowering plant in the borage family known by the common names small bluebells and long bluebells.
