This 2018 Belgian review subject was in part the transgenerational epigenetic effects of maternal obesity during pregnancy. The subject was tailored for the journal in which it appeared, Atherosclerosis, so other transgenerationally inherited epigenetic effects weren’t reviewed:

“The transgenerational impact of these alterations in methylation patterns are only shown in animal studies with HFD [high-fat diet] animals. In this respect the paternal influence also comes forward.

Alterations in methylation at the spermatozoa of male rats fed with a HFD were shown in combination with transgenerational metabolic effects, mainly on the female offspring. Methylation alterations in spermatozoa were also found in the male offspring of dams fed with HFD during their pregnancy. Consequent effects on the phenotype were again only shown in female offspring (until third generation).

A transgenerational inheritance through the female germline by mitochondrial inheritance has been suggested. A recent, small study in humans found altered mitochondrial functioning in the male offspring of overweight woman. A finding that has been confirmed in mice studies with a persistence of this transfer of aberrant oocyte mitochondria into the third generation.

The identification of a number of alterations in active cardiovascular microRNA species in the offspring of animals with obesity offer promising perspectives for the future.”

Evidence for transgenerational aspects of in utero programming included two studies I hadn’t previously curated:
